Which process involves the loss of heat due to air movement?

The process that involves the loss of heat due to air movement is convection. Convection occurs when warmer air rises and cooler air moves in to replace it, creating a current that carries heat away from a surface. This is particularly notable in environments where moving air can significantly change the temperature of an object or body, such as when a breeze blows over skin, leading to a cooling effect.

In contrast, conduction refers to the transfer of heat through direct contact between surfaces, while evaporation involves the loss of heat when a liquid (like sweat) changes to a vapor, using body heat in the process. Radiation is the transfer of heat energy through electromagnetic waves, which does not require a medium like air or direct contact. Therefore, convection is the accurate term that specifically highlights the role of air movement in facilitating heat loss.
