APPLICATIONS OF HEAT TRANSFERa) Applications of conduction

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.

APPLICATIONS OF CONVECTION2. Ventilation in homes which is used to keep rooms cool.Windows, doors or other vents can be opened or closed as needed to reduce the temperature and improve the quality of the air you're breathing.

APPLICATIONS OF CONVECTION3. Convection currents in a fridge.

C) APPLICATIONS OF RADIATION1. Why are houses painted white in hot countries?- White reflects heat radiation and so keeps the house cooler.
