Question

Give one use each for good and bad conductors of heat.

Answer 1

(a) Application of good conductors of heat:
Metals are used in making cooking utensils because they are good conductors of heat.
(b) Application of bad conductors of heat:
Handles of cooking utensils are generally made up of wood or plastic. This is because wood and plastic are poor conductors of heat. Hence, they protect our hands from getting burnt while holding the utensils.
