What are polymers? 2. What is ester? 3. Name the form of polyester which is replacing materials like glass and used for making bottles and jars. 4. What is rayon? 5. Why is it advised not to wear synthetic clothes while working in a laboratory or working with fire in the kitchen?

Answer 1

Answer:

A1

By definition, polymers are large molecules made by bonding (chemically linking) a series of building blocks. The word polymer comes from the Greek words for “many parts.” Each of those parts is scientists call a monomer (which in Greek means “one part”). Think of a polymer as a chain, with each of its links a monomer.

A2

an organic compound made by replacing the hydrogen of an acid by an alkyl or other organic group. Many naturally occurring fats

A3

The form of polyester which is replacing materials like glass and used for making bottles and jars is Polyethylene terephthalate (PET).

A4

Rayon is a manufactured fiber made from natural sources such as wood and agricultural products that are regenerated as cellulose fiber. The many types and grades of rayon can imitate the feel and texture of natural fibers such as silk, wool, cotton, and linen. Rayon is not considered to be synthetic.

A5

Synthetic fibers melt on heating. If they catch fire, they melt and stick to the body of the person wearing them. This is why it is advised not to wear clothes made of synthetic fiber while working in a kitchen or in a fire laboratory.
