Heat Transfer

Heat energy tends to flow away from a hotter object to its cooler surroundings. Heat energy can be transferred by radiation, conduction or convection. Thermal (infrared) radiation is the transfer of heat energy by the electromagnetic waves.

Heat Transfer

Conduction and convection involve the transfer of energy by particles.Conduction is the main form of heat transfer in solids. Convection is the main form of heat transfer in liquids and gasses.

Emission of thermal radiation occurs in solids, liquids and gasses. Any object can both absorb and emit heat radiation, wheather or not conduction or convection are also taking place. The bigger the temperature difference, the faster heat is transferred between the body and its surroundings
