Answer 2

Answer:

1.)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.

2.)Cooking pans have plastics handles. A metal handle would get almost as hot as the pot, while cooking something for an extended time. Wood and plastic does not conduct heat as well as metal, so a wooden or plastic handle is used in cookwares.
