Answer 1

Answer:

9 Why do metal saucepans have plastic or wooden handles? Metal is a good conductor of heat. If the handles of the saucepans were made of metal, they would become too hot to hold and that would be dangerous. Someone trying to hold a metal handle could drop the saucepan or receive a nasty burn.

10 Plastics are used for making variety of things- from a plastic bottle or a toy to very big bodies of any mechanism. If plastic wouldn't have been there, it would be harder to make such things which need plastic. > Plastics are used in things like covering of wires to act as insulators.
