Conduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated. Thermal radiation happens when accelerated charged particles release electromagnetic radiation, which can be felt as heat. video https://cdn.kastatic.org/googleusercontent/Hv0IoKraecmYL6pTEVTae9WcA_YqO7CTECyExWRxNubSsIz_lLldwJzKU-9lyrnn1meIsQR_7ZA93YKe2E-EzMzl Thermal conduction, convection, and radiation There are three forms of thermal energy transfer: conduction, convection, and radiation.

When two objects of different temperatures come into contact with one another, the particles at the surface of each object collide, resulting in the transfer of energy as heat. This process continues until thermal equilibrium is reached, at which point the average kinetic energies of the particles—and therefore the temperatures of the objects—is the same.
