Convection is the transfer of heat through liquids or gases. Example: When cold air enters your home, it mixes with warm air. Heat energy is transferred to the cooler air, and the overall temperature of the room is lowered. Result: More energy is required to replace the heat transferred to the cooler air.

Ans 3:

Class : Class 5
