Answer :
Answer:
b) Convection
Explanation:
An air conditioner cools a room using convection method. Therefore, the option (b) is the correct answer.
An air conditioner cools a room primarily through convection, which involves the movement and circulation of air or another fluid to transfer heat. Convection is one of three heat transfer methods, alongside conduction and radiation.
An air conditioner cools a room using the method of convection. This process involves the removal of warm air from the room and the circulation of cooler air by a fluid medium, which is typically a refrigerant within the AC system. This cooler air absorbs heat from the surroundings, and as it becomes warmer, it is drawn back into the air conditioner to be cooled down again. Heat transfer by circulation of a fluid like this is classified as convection and is one of the three different heat transfer methods, the others being conduction and radiation. Unlike convection, conduction involves direct contact between two surfaces, and radiation does not need an intervening medium to transfer energy.
