Question 11.
Should the handle and bristles of a toothbrush be made of the same material? Explain your answer.
Answer:
No, the handle and bristles of a toothbrush should not be made of the same material. This is because our gums are soft and the bristles should be made of soft material so that it does not harm the gums. On the other hand, the handles should be made up of hard material so that it can give a firm grip.
Question 12.
‘Avoid plastics as far as possible’. Comment on this advice.
Answer:
Plastics must be avoided as far as possible. The materials made of plastics are non-biodegradable. The use of plastics has a bad effect on the environment. When the plastics are burnt, it releases a lot of poisonous fumes into the atmosphere causing air pollution. These plastic materials when eat up by the animals (like cows), choke their respiratory system. This can cause death of these animals. The waste plastic articles thrown here and there carelessly get into dirty water drains and sewers, and block them. In a nutshell, plastics can be considered a threat to our environment.

Synthetic Fibres and Plastics Class 8 Science NCERT Intext Activities Solved
Activity 1 (NCERT Textbook, Page 34)
Take an iron stand with a clamp. Take a cotton thread of about 60 cm length. Tie it to the clamp so that it hangs freely from it as shown in Fig. 3.3.
At the free end suspend a pan so that weight can be placed in it. Add weight one by one till the thread breaks. Note down the total weight required to break the thread. This weight indicates the strength of the fibre. Repeat the same activity with threads of wool, polyester, silk and nylon. Tabulate the data as shown in Table 3.1. Arrange the threads in order of their increasing strength.
Observation Table 3.1
S. No. | Type of Thread/ Fibre | Total Weight required to break the thread |
1. | Cotton | 12 gm |
2. | Wool | 70 gm |
3. | Silk | 50 gm |
4. | Nylon | 100 gm |
(Precaution: Note that all threads should be of the same length and most of the same thickness.)
Activity 2 (NCERT Textbook, Page 36)
Take two cloth pieces of the same size, roughly half a metre square each. One of these should be from natural fibre. The other could be a synthetic fibre. You can take the help of your parents in selecting these pieces. Soak the pieces in different mugs each containing the same amount of water. Take the pieces out of the containers after five minutes and spread them in the sun for a few minutes. Compare the volume of the water remaining in each container.
Solution:
It is observed that the volume of water of the container in which natural fibre is soaked contains less water as compared to the container in which synthetic fibre is soaked. Thus, natural fibre absorbs more water as compared to synthetic fibre. When both the fibres were spread in the sun, it was observed that synthetic fibre took less time to dry than natural fibre.

These days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres. Discuss the reasons for this. Ans: Clothes purely made of synthetic fibres are not comfortable to wear so they are mixed with natural fibres. Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing 4. Differentiate between thermoplastics and thermosetting plastics. Give two examples of each. Ans: Thermosetting plastics are kind of plastic which once moulded cannot moulded again by heating. for example : Bakellite , melanin, Formaldehyde Thermoplastic Plastic are kind of plastic which can be moulded again and again by heating and easily reused.For example :PVS, Polysterine , nylon , polythine 5. Plastics are very useful materials. Why then is there concern today about their increasing use. Ans: This is because plastics are non biodegradable and improper disposal cause environmental problems. The burning plastic releases lots of poisonous fumes into the atmosphere causing air pollution. 6. List three steps you can take to reduce the danger that plastics pose to the environment. Ans: The following three steps can be taken to reduce the danger that plastics pose to the environment: LONG-ANSWER QUESTIONS: Answer in about 60 words. 1.. How is rayon made? Why is it called artificial silk? List its important properties and uses. Ans: Rayon is made by dissolving wood pulp in an alkaline solution. The thick liquid thus produced is passed through tiny holes to make fibres, which are hardened by passing them through a bath of sulphuric acid. The fibres are then spun into yarns and woven into clothes. Rayon is called artificial silk because it is produced from naturally occurring polymers and looks like silk. The uses of rayon are: 2.

Ans: The four properties of plastics are: 3, Give the characteristic properties and important uses of the following: Ans: (a) The properties and uses of polythene are as follows: Uses: Polythene sheets are used for the packaging of liquids such as milk. Polythene pipes are used to transport liquids such as oil and water. Polythene containers are used to store liquids. (b) The properties and uses of polystyrene are as follows: HOTS QUESTIONS: Think and answer. 1. Do you think rayon when burnt will stick to the body like other synthetic fibres? Ans: Synthetic fibres catch fire very easily. They melt on heating and stick to the body of the person wearing them. However, rayon is regenerated from cellulose and it doesn’t melt on burning, rather it flares up like paper and smells like it. 2. Burning cotton smells like burning paper, whereas burning wool smells like burning hair. Why? Ans: Cotton smells like burning paper because both cotton and paper are extracted from plants and constitute mainly cellulose, whereas burning wool smells like burning hair because both wool and hair are extracted from animals and both have sulphur in them. 3. Which property of plastics makes them so useful but also makes them an environmental hazard? Ans: Plastics are nonreactive. They last much longer than any other material. They cannot be decomposed by bacteria and so are no biodegradable in nature. These properties make plastics useful but also make them as environmental hazard. 4. Clay is a ‘plastic’ material. Does this imply that it is a polymer? Ans: Clay is a ‘plastic’ material because we can mould it into different shapes, which is a property of plastic. But clay is not a polymer because polymers are made up of monomer units while clay is not made up of monomer units. Clay is a mixture of compounds. 5. Ankit was learning how to cook. His father strictly told him not to wear nylon clothes in the kitchen. Why? Ans: Nylon is a synthetic fibre. Synthetic fibres catch fire easily. They are inflammable. They melt on heating and stick to the body of the person wearing them which causes severe burn injuries. Therefore, these type of clothes are not suitable in a kitchen. |
