SUMMARY
Temperature is defined as the measure of average kinetic energy of gas molecules, directly correlating to the sensation of hotness or coldness. The heating effect experienced is a result of molecular motion, which generates heat through three primary mechanisms: conduction, convection, and radiation. Conduction occurs via direct contact, where heat transfers from a hot body to a cooler one, such as a hand. Convection involves the movement of warm air, which rises and is replaced by cooler air, while radiation allows for energy transfer through infra-red waves.
