(a)Saucepanhandles

(b)Electricplugs/switches/plugboards​

Answer 1

Answer:

a) Thermosetting plastics are used in saucepan handles because they do not soften on heating and also they cannot be bent easily. These plastics like bakelite are poor conductors of heat.

b) Thermosetting plastics are used in electric plugs/switches/plug boards as they are bad conductors of electricity. They do not get moulded. Also,they are hard and strong.

Answer 2

sauce pan handles and electric plugs are made up of plastic because plastic is the poor conductor or insulator  of electricity and heat so it helps in safeguarding us by not getting electric shocks..

or  reducing the risk of electrocution.
