Question 2.
“Grouping of objects helps the shopkeeper.” Justify the statement.
Answer:
The grouping of objects in proper way makes it easier to work. When we got to purchase something, the shopkeeper locates it easily, because there are separate shelves to put various items and similar things are kept at one place. If he randomly places all of these, he would never be able to find it so quickly and easily.

Answer:
Some important properties of matter are discussed below:

1. Appearance: Materials can be classified on the basis of their appearance. Different materials have different appearances.
2. Lustre: Materials can be classified on the basis of their lustre. Some.shine a lot whereas others are quite dull.
3. Solubility in water: On the basis of solubility in water, substances are classified as soluble and insoluble.

The plants and animals which live in water use the oxygen dissolved in water for respiration. Thus, oxygen dissolved in water is very important for the survival of animals and plants that live in water.

Carbon dioxide gas is also soluble in water. The plants which live in water use the carbon dioxide gas dissolved in water for the process of photosynthesis.

Question 3.
In which season is cotton planted? What is its course of growth?
Answer:
It is planted in early spring. Cotton plants grow steadily and soon become bushes of 3 to 6 feet high. After about 2 months, they bear white or yellowish flowers which turn pink or red after a few days. The petals of the flowers fall, leaving behind tiny green seeds. This later grows into spherical shaped structure of the size of wallnut, which is called cotton ball.

As the cotton balls grow steadily the seeds and fibres grow inside. On maturing, the green balls begin to turn brown. On complete maturation, they become ready to burst open, exposing the white fibres. As the fibres dry in the sun, they become fluffy.

Question 4.
What is retting? Explain how fibres are obtained from the jute plants.
Answer:
Jute plants are cut at the flowering stage when plants are 8-10 feet high. The cut plants are grouped at different places in the field for few days when most of the leaves dry up and fall down. The plants are now tied into small bundles.

The bundles are made to sink in stagnant water of a pond for few days when the gummy skin rots out to separate fibres. This process is called retting. Fibre is extracted from the retted jute by hand, with jerks and pulls. The dried fibres are then tied together in small bundles.

Question 5.
What is a loom? For what purpose is it used? What is the difference between handloom and power loom?

2. Weaving: The process of making fabric by crossing two sets of yarns over and under each other is called weaving. This process is used for making shirts, trousers, T-shirts, etc.

Question 7.
What are the three stages in history of the development of clothing material?
Answer:
In terms of raw materials, cloth making was developed in three stages. The first stage was cloth from plant fibres, such as flax, cotton, nettles and inner bark of the trees. The second stage began with the use of animal fibres especially wool and silk. Silk came to various parts of the world from China.

The third stage in the history of clothing began in the late 19th century with the development of man-made or synthetic fibres like rayon, nylon and polyester. Now man-made fibres combined with other animals with or without plant fibres are used for making clothes for improved strength, wearing ability and other qualities.
