Class 7 Science Chapter 5 Acids Bases And Salts Extra Questions Question 18.
Three liquids are given to you. One is hydrochloric acid, another is sodium hydroxide and third is a sugar solution. How will you identify them? You have only turmeric indicator.
Answer:
Turmeric solution turns red on coming in contact with bases. It is not affected by acids and neutral substances. At first we will identify the base. Samples of the given three liquids are tested by adding a small quantity of turmeric to them.

The liquid in which the colour of turmeric changes from yellow to red, is a base, i.e., sodium hydroxide solution. Then, one of the remaining two unidentified solutions is added to it gradually. If the solution turns yellow again, the added liquid is hydrochloric acid (because it neutralises the base). Otherwise, the added liquid is sugar solution.

Question 23.
When a candle burns, both physical and chemical changes take place. Identify these changes. Give another example of a familiar process in which both the chemical and physical changes take place.
Answer:
Physical changes: The wax of the candle first melts, then vaporises and burns.
Melting of wax is a physical change since molten wax can be solidified back to the wax and there is no new substance formed.

Chemical changes: When wax vapours burn, smoke and carbon dioxide are formed which are new substances. So, it is a chemical change.

Example: Lightning torch bulb using dry cell is another example where both physical and chemical changes take place.

The lighting of the bulb is physical change since no new substance is formed there. The current from the dry cell is obtained by the chemical substances inside it. Here, the chemicals in the cell react with each other and produce light substances and hence the cell ultimately becomes useless. So, it is a chemical change.

Question 24.

Question 29.
Explain why rusting of iron objects is faster in coastal areas than in deserts.
Answer:
In coastal areas, there is more moisture in air due to the presence of sea. But in deserts, there is a scarcity of water and hence air is almost dry there. Both air and moisture are necessary conditions for rusting. So, rusting is faster in coastal areas than in deserts.

Question 30.
Describe two changes that are harmful. Explain why you consider them harmful? How can you prevent them?
Answer:
(i) Rusting: If a piece of iron is left in open for some time, it acquires a film of brownish substance. This substance is called rust and the process is called rusting.
Rusting is harmful because it destroys the iron objects. Iron is the most widely used metal and so rusting is such a serious problem. Prevention of rusting: Rusting can be prevented by preventing iron particles from coming in contact with oxygen, or water, or both.

  • One simple way is to apply a coat of paint or grease. In fact, these coats should be applied regularly to prevent rusting.
  • Another way is galvanisation, i.e., to deposit a layer of a metal like chromium or zinc on. iron.

(ii) Spoilage of food: Food items when kept carelessly, get spoiled. This is a chemical change and obviously harmful for us. Food is spoiled by microorganisms.

Prevention of food spoilage: Microorganisms do not survive at high or low temperatures. So, food items stored in refrigerator do not spoil. Also we should keep them covered so that microorganisms do not get any chance to enter and spoil them.

Land.

Heat And Temperature Class 7 Questions And Answers Question 6.
Why is range of a clinical thermometer is chosen to be 35°C to 42°C?
Answer:
The clinical thermometer is designed to measure the temperature of human body only. The temperature of human body normally does not go below 35°C or above 42 GC. That is why the clinical thermometer has the range 35°C to 42°C.

Heat Class 7 Questions And Answers Question 7.
What caution do you suggest regarding a clinical thermometer?
Answer:
A clinical thermometer should not be used for measuring the temperature of any object other than the human body. Also, avoid keeping the thermometer in the sun or near a flame. It may break.

Class 7 Science Chapter 4 Extra Questions And Answers Question 8.
Why should you wear white clothes in summer and black clothes in winter?
Answer:
Dark surfaces absorb more heat and, therefore, we feel comfortable with dark-coloured clothes in the winter. Light coloured clothes reflect most of the heat that falls on them and, therefore, we feel more comfortable wearing them in the summer.

Heat Extra Questions Class 7 Question 9.
Describe the construction of a clinical thermometer.
Answer:
A clinical thermometer consists of a long, narrow, uniform glass tube. It has a bulb at one end. This bulb contains mercury. Outside the bulb, a small shining thread of mercury can be seen. There is also a Celsius scale on the thermometer.

Ncert Class 7 Science Chapter 4 Extra Questions Question 10.
How do land and sea breezes blow?
Answer:
During the day, the land gets heated faster than the water. The air over the land becomes hotter and rises up. The cooler air from the sea rushes in towards the land to take its place. The air forms the sea breeze. The warm air from the land moves towards the sea to complete the cycle.

At night it is exactly the reverse. The water cools down more slowly than the land. So, the cool air from the land moves towards the sea. This forms the land breeze.

Class 7 Science Chapter 4 Extra Question Answer Question 12.
Boojho says, “My left hand tells me that the water in mug C is hot and the right-hand tells mc that the same water is cold. What should I conclude ?“
Answer:
Both conclusions are true relative to each hand. But a single conclusion cannot be drawn from the given information. This is all due to relative temperature.

Class 7 Science Ch 4 Extra Questions Question 13.
Boojho got a naughty idea. He wanted to measure the temperature of hot milk using a clinical thermometer. Paheli stopped him from doing so. Why?
Answer:
The clinical thermometer is designed to measure the human body temperature which ranges from 35CC to 42°C. Hot milk has a temperature range of 80°C to 100°C, which is quite high. This may break the thermometer because of abrupt mercury rise.

Ncert Solutions For Class 7 Science Chapter 4 Heat Extra Questions Question 14.
Boojho wonders why the level of mercury should change at all when the bulb of the thermometer is brought in contact with another object?
Answer:
The temperature of other objects may not be the same as that of the bulb of the thermometer. When bulb is brought in contact with that object, the temperature of the bulls changes. So the level of mercury also changes.

Questions On Heat For Class 7 Question 15.
Can you lift a hot pan by holding it from the handle without getting hurt?
Answer:
Yes. If the handle is insulated with the help of a cloth or insulated material like plastic or wood, the pan can be lifted without getting hurt.

Class 7 Science Heat Extra Questions Question 16.
Do these activities suggest to you the reason why it more comfortable to wear white or light-coloured clothes in the summer and dark-coloured clothes in the winter?
Answer:
Dark surfaces absorb more heat and, therefore, we feel comfortable with dark coloured clothes in the winter. Light coloured clothes reflect most of the heat that falls on them and, therefore, we feel more comfortable wearing them in the summer.

Question 17.
Suppose you are given the choice in winter of using one thick blanket or two thin blankets joined together. What would
you choose and why?
Answer:
I would choose two thin bi anklets joined together. This is because there would be a layer of air in between the blankets. The trapped air, which is a bad conductor of heat, keeps it warmer.

By going through these Online Education CBSE Class 7 Sanskrit Notes Chapter 12 विद्याधनम् Summary, Notes, word meanings, translation in Hindi, students can recall all the concepts quickly.

Online Education for Class 7 Sanskrit Chapter 12 विद्याधनम् Summary Notes

विद्याधनम् पाठ का परिचय

पाठ का परिचय (Introduction of the Lesson) प्रस्तुत पाठ में श्लोकों के द्वारा विद्या के महत्त्व को बताया गया है। विद्या मनुष्य का सर्वश्रेष्ठ धन है। विद्यावान् व्यक्ति का सर्वत्र सम्मान होता है, विद्या मनुष्य का सबसे बड़ा गुण है। विद्या कल्पतरु के समान मनुष्य के सभी कार्य पूर्ण करती है। विद्याहीन मनुष्य पशु के समान होता है। अतः मनुष्य को श्रेष्ठ प्राणी बनने के लिए विद्या रूपी धन को संचित करना चाहिए।

विद्याधनम् Summary

विद्या कल्पलता की तरह होती है। इस पाठ में विद्या का महत्त्व बताया गया है। यथा विद्या को चोर चुरा नहीं सकता, राजा छीन नहीं सकता और भाई बाँट नहीं सकता। विद्या सभी धनों में श्रेष्ठ है। इसे व्यय किए जाने पर यह बढ़ती है। विद्या मनुष्य का सौन्दर्य है। यह गुप्त से गुप्त धन है। यह अनेक भोगों को देने वाली है तथा सुख प्रदान करने वाली है। राजाओं में ज्ञान की पूजा होती है तथा धन की नहीं।

मनुष्य की शोभा न तो हार से बढ़ती है और न ही पुष्प अथवा अङ्गराग के द्वारा बढ़ती है। मनुष्य की शोभा ज्ञान से बढ़ती विद्या माता की तरह रक्षा करती है, पिता की तरह हित का साधन करती है। यह शोभा को बढ़ाती है। विद्या मनुष्य का सभी प्रकार से भला करती है।

विद्याधनम् Word Meanings Translation in Hindi

(क) न चौरहार्यं न च राजहार्य
न भ्रातभाज्यं न च भारकारि।
व्यये कृते वर्धत एव नित्यं
विद्याधनं सर्वधनप्रधानम्॥1॥

शब्दार्थाः (Word Meanings) :
चौरहार्यम्-चोरों के द्वारा चुराने योग्य (can be stolen by thieves), राजहार्यम्-राजा के द्वारा छीनने योग्य (can be snatched by king), भ्रातृभाज्यम्-भाइयों के द्वारा बाँटने योग्य (can be divided by brothers), भारकारि-भार (बोझ) बढ़ाने वाली [(that) which increases weight], वर्धते-बढ़ता है (increases), नित्यं-हमेशा (always), प्रधानम् प्रमुख (सर्वोत्तम) (best).

सरलार्थ :
न चोरों के द्वारा चुराने योग्य है और न राजा के द्वारा छीनने योग्य है, न भाइयों के द्वारा बाँटने योग्य है और न भार (बोझ) बढ़ाने वाला है। हमेशा खर्च करने पर बढ़ता ही है। विद्या का धन सभी धनों में प्रमुख (सर्वोत्तम) है।

English Translation :
Neither can it be stolen by thieves nor can it be snatched by the king, nor can it be divided by brothers and nor does it weight. It always grows on spending (using). The wealth of knowledge is the best of all the wealth.

(ख) विद्या नाम नरस्य रूपमधिकं प्रच्छन्नगुप्तं धनम्
विद्या भोगकरी यशः सुखकरी विद्या गुरूणां गुरुः।
विद्या बन्धुजनो विदेशगमने विद्या परा देवता
विद्या राजसु पूज्यते न हि धनं विद्या-विहीनः पशुः ॥2॥

शब्दार्थाः (Word Meanings) :
प्रच्छन्नगुप्तम्-अत्यन्त गुप्त (hidden), भोगकरी-भोग का साधन उपलब्ध कराने वाली [(it) helps provide the means of pleasure], परा-सबसे बड़ी (greatest), गुरूणां-गुरुओं का (of teachers), राजसु-राजाओं में (among kings), विद्या-विहीनः-विद्या से रहित (without knowledge).

सरलार्थ :
विद्या मनुष्य का अधिक (अच्छा) स्वरूप है, छुपा हुआ गोपनीय धन है, विद्या भोग का साधन उपलब्ध कराने वाली है, कीर्ति और सुख प्रदान कराने वाली है, विद्या गुरुओं का गुरु है। विद्या विदेश जाने पर बन्धु (मित्र) के समान होती है, विद्या सबसे बड़ा देवता है। विद्या राजाओं में पूजी जाती है, धन नहीं। विद्या से रहित (मनुष्य) पशु के समान होता है।

English Translation :
Knowledge is a person’s best identity, (it) is the hidden wealth, (it) helps provide the means of pleasure, (it) provides fame and comfort/ happiness, knowledge is the teacher of teachers. On going to foreign country knowl edge is like a friend. Knowledge is the greatest god/divinity. Knowledge is worshipped among kings, not wealth. A person without knowledge is like an animal.

(ग) केयूराः न विभूषयन्ति पुरुषं हारा न चन्द्रोज्ज्वला
न स्नानं न विलेपनं न कुसुमं नालङ्कता मूर्धजाः।
वाण्येका समलङ्करोति पुरुषं या संस्कृता धार्यते
क्षीयन्तेऽखिलभूषणानि सततं वाग्भूषणं भूषणम् ॥3॥

शब्दार्थाः (Word Meanings):
केयूरा:-बाजूबन्द (Bracelets), चन्द्रोज्ज्वला (चन्द्र+उज्ज्वला) चन्द्रमा के समान चमकदार (bright as the moon), विलेपनम्-शरीर पर लेप करने योग्य सुगन्धित-द्रव्य (चन्दन, केसर आदि) (scented material for anointing the body (hair) like sandal, saffron etc.), मूर्धजा:-बाल/वेणी/चोटी (plait), नालङ्कृता (न + अलङ्कृता)-नहीं सजाया हुआ (not decorated), वाण्येका (वाणी+एका)-एकमात्र वाणी (only speech), समलङ्करोति ( सम्+अलङ्करोति) अच्छी तरह सुशोभित करती है (adorns well), संस्कृता-परिष्कृत (संस्कारयुक्त) (Refined), धार्यते धारण की जाती है (is learnt), क्षीयन्तेऽखिलभूषणानि (क्षीयन्ते अखिलभूषणानि)-सम्पूर्ण आभूषण नष्ट हो जाते हैं (all ornaments decay), वाग्भूषणम्-वाणी का आभूषण (ornament of speech).

सरलार्थ :
मनुष्य को न बाजूबन्द सुशोभित करते हैं, न चन्द्रमा के समान चमकदार हार, न स्नान, न शरीर पर सुगन्धित लेपन (चन्दन, केसर आदि), न बालों/चोटी में सजाए हुए फूल सुशोभित करते हैं और ना हीं सजाई गई चोटी ही। मनुष्य को एकमात्र वाणी, भली प्रकार सुशोभित करती है, जो परिष्कृत (संस्कारयुक्त) रूप में धारण की जाती है (व्यवहार में लाई जाती है)। अन्य सभी आभूषण नष्ट होते हैं, (परन्तु) वाणी का आभूषण सदैव रहने वाला आभूषण है।

English Translation :
Neither bracelet nor bright as moon necklaces, nor bath, nor scented anointing on the body (sandal, saffron etc.), nor flowers decorating the hair plait adorn a person. Only speech which is learnt refined, adorns a person well. All other ornaments are destroyed, the ornament of speech is an everlasting ornament.

(घ) विद्या नाम नरस्य कीर्तिरतुला भाग्यक्षये चाश्रयः
धेनुः कामदुधा रतिश्च विरहे नेत्रं तृतीयं च सा।
सत्कारायतनं कुलस्य महिमा रत्नैर्विना भूषणम्
तस्मादन्यमुपेक्ष्य सर्वविषयं विद्याधिकारं कुरु॥4॥

शब्दार्थाः (Word Meanings) :
कीर्तिरतुला (कीर्तिः + अतुला)-अतुल्य यश (incredible fame), कामदुधा-इच्छाओं की पूर्ति करने वाली (one that fulfils all aspiration/desires), रतिश्च (रतिः + च)-और प्रेम (love). सत्कारायतनम (सत्कार + आयतनम)-सम्मान का स्थान अर्थात् सम्मान प्रदान करने वाली (dwelling place of fame/giver of fame), रत्नौविना (रलैः+विना) (मूल्यवान.) रत्नों के बिना (without jewels), विद्याधिकारम्-(विद्या + अधिकारम्) विद्या पर प्रभुत्व (mastery over learning).

सरलार्थ :
विद्या वास्तव में (नाम) मनुष्य की अतुल्य कीर्ति है, भाग्यक्षय (बदकिस्मती) होने पर एक आश्रय/सहारा है। कामनापूर्ति करने वाली गाय अर्थात् कामधेनु है। विरह में प्रेम करती है और वही मनुष्य की तीसरी आँख होती है। सम्मान का स्थान है। कुल की महिमा है, (बहुमूल्य) रत्नों के बिना भी आभूषण है। अतः अन्य सब बातों को छोड़ विद्या पर अपना प्रभुत्व कर लो। .

English Translation :
Learning is indeed man’s incredible fame (ie learning bring unparalleled fame) It is a support in times of adverse circumstances. It is a cow that fulfils all desires, (satisfying) love in times of separation; it is the third eye (that can perceive everything beyond normal vision). It is the giver of honour/fame. It is the prestige of family. It is an adornment without any jewels. Hence, ignoring everything gains mastery over learning.

Question 16.
If the pitcher plant is green and carries out photosynthesis, then why and how does it feed on insects?
Answer:
The pitcher plant is green and carries out photosynthesis. Thus, it gets its nutrition by this process. But it does not get nitrogen which is required for its growth from the soil in which it grows.
Nutrition In Plants For Class 7 Questions With Answers
The pitcher plant have pitcher like structures which are the modified parts of the leaves. The apex of the leaf forms a lid which can open and close the mouth of the pitcher. Inside the pitcher are hair which are directed downwards. When an insect lands in the pitcher, the lid closes and the trapped insect gets entangled into the hair. The insect is digested by the* digestive juices secreted in the pitcher.

Question 17.
Boojho wants to know how water and minerals absorbed by roots reach the leaves.
Answer:
Water and minerals are transported to the leaves by the vessels which run like pipes throughout the roots, stems, and leaves of the plant. They form a continuous path or passage for the nutrients to reach from the roots to the leaves.

Question 18.
From where do the plants obtain nitrogen?
Answer:
Soil has certain bacteria that convert gaseous nitrogen into a usable form and release it into the soil. These soluble forms are absorbed by the plants along with water.

Question 19.
There are some plants which do not have chlorophyll. How do they survive and from where do they derive nutrition?
Answer:
They have different mechanisms fir deriving nutrition from other organisms. They are heterotrophs. They take readym&de food from the plant on which it is climbing.

Question 20.
Are we and the other animals also parasites for the plants?
Answer:
No, parasites live on the host and derive nutrition from it. They do not eat any body part of the host. But, man or other animals (like cow) eat plants or plant products. In return, man and the other animals provide CO2 to the plant
for photosynthesis.

Question 21.
Paheli wants to know whether mosquitoes, bed bugs, lice and leeches that suck our blood are also parasites.
Answer:
Lice are parasites because they live on another organisms like human beings and other animals and get their nutrition without benefitting the host. Mosquitoes, bed bugs and leeches though suck blood from other organisms’ body are not parasites as they do not live on the host.

Question 23.
How would you test the presence of starch in leaves?
Answer:
When iodine comes in contact with starch, a dark blue-black colour appears. By dropping iodine solution on the leaves, we can check the presence of starch.

Nutrition in Plants Class 7 Extra Questions and Answers Science Chapter 1

Experiments:
(1)
Aim: To show that sunlight is necessary for photosynthesis.
Requirements: Two potted plants, iodine solution and a dropper.

Procedure:

  • One potted plant is kept in sunlight for three days.
  • The other potted plant is kept in complete darkness.
  • After three days, with the help of a dropper, a few drops of iodine solution are dropped Oflone leaf of each of the potted plants.

Observation: Blue-black colour appears on the leaf of plant kept in sunlight while nothing happens in the leaf of plant kept in dark.

Conclusion: Iodine solution turns blue-black when comes in contact with starch. So, the leaf of the plant kept in sunlight turns blue-black but no starch was formed in plant kept in darkness. This proves that sunlight is necessary for photosynthesis.

(2)
Aim: To show that chlorophyll is necessary for photosynthesis.
Requirements: Plant with variegated leaves, iodine solution and a dropper.

Procedure:

  • The plant with variegated leaf is kept in sunlight or a few hours.
  • Now with the help of a dropper, a few drops of iodine solution is dropped on one leaf so that it drenched out the leaf completely.

Observation: The green part of the leaf turns blue-black but the other coloured part remains as it is.
Conclusion: Photosynthesis occurs in green parts only. So, chlorophyll is necessary for photosynthesis.
