WebThere are three forms of thermal energy transfer: conduction, convection, and radiation. 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. Web18 jan. 2024 · Heat transfer by radiation Radiation is a heat flux through electromagnetic waves through space. This kind of heat transfer occurs without an intervening medium. Hot objects emit infra-red radiation from their surface, which in return heats any matter surrounding them. Particles emit and receive even when the temperature stable.
