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.

Blackbodies do not perpetually warm up as they absorb light because the accelerating charged particles inside them radiate their own light. The spectrum radiated by a blackbody depends only on its temperature. The hotter a blackbody is, the more intense its radiation is, and the shorter its peak wavelength is. The relationship between temperature and spectrum is used to estimate a star's surface temperature based on its color.
