Question

What are biodegradable and non-bindegradable
material

Which is called artificial silk

What is polymerisation,

Expand PET

write any 2 advantages of synthetic fibers

What are the thermoplastics the thermsetting plastics

expand PVC ​

Answer 1

Answer:

:biodegradable waste are natural waste can be recycle and non-biodegradable waste is inversely proportional to biodegradable waste.

:nylon.

process of preparing polymers in chain.

PET: ---

•can be dried easily,

•cheap.

Answer 2

Answer:

1 ) Biodegradable wastes

Waste meterials which can be broken down into harmless substances in nature in due course of time by the action of microorganisms wastes

Non biodegradable wastes

Waste materials which cannot be broken down into harmless substances by the action of microorganisms in nature are called non biodegradable wastes .

2 ) Artificial silk or art silk is any synthetic fibre which resembles silk , but typically costs less to produce .

3 ) Polymerisation

polymers are formed when small molecules know as monomers join together

All the monomers in this kind of Polymerisation must contain C = C

Each small monomer becomes a part of the polymer

4 ) PET - polyethylene Terephthalate

5 ) Synthetic fibres do not depend either on an agricultural crop or on animal farming

They are generally cheaper than natural fibre

Synthetic fibres possess unique characteristics which make them popular dress meterial .

7 ) Polyvinyl chloride

Sorry for me dont no 6 question

hope helpful for you
