nehabhabhi takes two type of fibER natural;synthetic. she does not know which one is nATURAL FIBER WHICH ACTIVITY YOU WILL SUGGEST TO IDENTIFY FIBRES

Answer»

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.
