Conduction
Conduction is the transfer of heat through particle collisions.
Convection
Convection is the transfer of thermal energy through the movement of fluid particles, driven by differences in density.
Heat transfer
The movement of thermal energy from one object or region to another due to a temperature difference.
Radiation
Transfer of heat through infrared radiation, where the body radiates heat into the surroundings or absorbs heat from warmer objects or the sun.
Thermal radiation
Electromagnetic radiation emitted by matter due to its temperature, transferring energy without needing contact or a material medium.
