Question 3
1 / -0

Plastics are mainly used by everyone because:

A
They are cheap

B
Easy to handle

C
Light weight

D
All of the above

Solution

Plastics find many applications in day-to-day life because of various reasons as:
1) They are cheap compared to metals.
2) Easy to handle, unlike ceramics and glass which are brittle.
3) Lightweight materials and easy to carry.
4) High durability.

Therefore option $$D$$ is correct.
Question 4
1 / -0

Which of the following substance is biodegradable?

A
Cloth

B
Thermosetting plastic

C
Thermoplastic

D
PVC pipes
Solution
Biodegradable wastes are such waste materials that are degraded by natural factors like microbes (e.g. bacteria, fungi), abiotic elements like temperature, pH, oxygen, etc. Example: kitchen wastes and other natural wastes.
Cloth is a natural polymer made from cellulose.
Cotton, silk, wool is biodegradable while plastics (thermoplastic, thermosetting plastics, PVC) are synthetic polymers and are non-biodegradable.
Hence, option A is correct.
Question 5
1 / -0

A material which is not easily decomposed by natural processes is termed as :

A
biodegradable material

B
non-biodegradable material

C
recycled material

D
natural material

Solution

A material which is not easily decomposed by natural processes is termed as $$\text {non-biodegradable material}$$. Examples are polyethene, PVC, PS. It takes many years for decomposition. Hence, option B is correct.
Question 6
1 / -0

Why plastic containers are favoured for storing food?

A
Plastics are light in weight

B
Plastic is a strong and durable material

C
Plastics are easy to handle

D
All of the above

Solution

Question 8
1 / -0

Like synthetic fibres, plastic is also a:

A
polymer

B
polythene

C
polycot

D
acrylic

Solution

$$\text { Sulution:- Synthetic fibres are also called man- } \\$$
$$\text { made or artificial fibres, they are } \\$$
$$\text { synthesised from raw material called petrochemicals } \\$$
$$\text { and like synthetic fibres, plastic is also a } \\$$
$$\text { - polymer. Yes, they are called as man made } \\$$
$$\text { or artificial fibres. }\\$$
$$\text {Hence option (A) is correct.}$$
Question 9
1 / -0

Which synthetic fibre is used in making ropes for rock climbing and parachutes ?

A
Nylon

B
Rayon

C
Polycot

D
Jute

Solution

Nylon fibre is used in making ropes for rock climbing and parachutes because it is a very strong fibre.
Question 10
1 / -0

Telephone instruments, plastic toys, ball point pens, plastic bowls are examples of:

A
Thermoplastics

B
Thermosetting plastic

C
Polyester

D
None of the above

Solution

Telephone instruments, plastic toys, ball point pens, plastic bowls are thermoplastics and so can be recycled.

Cooker handles, carry bags, plastic covering on electric wire, plastic chains, etc are thermosetting plastics and so cannot be recycled.
