Uses of good conductors of heat:
1. Cooking utensils e.g. saucepans, frying pans, boilers, base of electric irons.
-
USES OF GOOD CONDUCTORS OF HEAT
-
USES OF BAD CONDUCTORS OF HEAT3. Handles of cooking utensils are made of wood or plastic.
-
b) Applications of convection1. The heating coil of an electric kettle is placed at the bottom so that convection current can occur.
-
