Question

Explain with help of an activity that synthetic fibres melt on heating.​

Answer 1

Answer:

 A synthetic fibre is also a chain or small units joined together. Each small unit is actually a chemical substance. Many such small units combine to form a large single unit called a polymer.

The word ‘polymer’ comes from two Greek words; poly meaning many and mere meaning part/unit. So, a polymer is made of many repeating units.

Polymers occur in nature also. Cotton, for example, is a polymer called cellulose. Cellulose is made up of a large number of glucose units.

Answer 2

Answer:

Synthetic fibres are made up of small atoms or units.
