Question

Nehabhabhi takes two types of fiber, natural and synthetic. She does not know

which one is natural fiber and which is synthetic fiber. Which activity you will suggest

to identify the fibers​

Answer 1

I will suggest her to burn a small piece of fabric of both categories to test whether it's a natural fibre or synthetic fibre.

• When natural fibres are burnt their ash crumbles on touching.
• While synthetic fibres show the characteristics of plastics on burning. As we must have observed that plastic when burnt do not turn into ash instead thry curl up.
• Therefore she can differentiate between natural and synthetic fibres by burning small pieces of each of them.
