Answer 1

Explanation:

Clothes purely made of synthetic fibres are not comfortable in hot and humid weather as they are water resistant and do not absorb sweat from the body. They catch fire easily and stick to the body and cause severe burns and injuries. Therefore, they are not suitable in kitchen and laboratories.

Answer 2

Answer:

It melts on catching fire (option C [3rd])

Explanation:

The synthetic fibres melt on heating. This is actually a disadvantage with synthetic fibres.  

If the cloth catches fire it can be very disastrous. The fabric melts and sticks to the body of the person wearing it. It is therefore advised not to wear synthetic clothes while working in a laboratory or working with fire in the kitchen.
