Molecule motions and collisions make average random translational kinetic energy {temperature, heat}|. Average gas-molecule velocity at room temperature is 500 meters per second.
Materials can have no kinetic energy and no heat potential energy {absolute zero temperature}|, at -273.16 degrees Celsius.
Temperature scales {Celsius, temperature scale}| {centigrade} can set water freezing point to 0 C and boiling point to 100 C, at sea level.
Temperature scales {Kelvin, temperature}| can set water freezing point to 273 K and boiling point to 373 K, at sea level.
Surface temperature is proportional to energy emitted per unit area {Stefan's law} {Stefan law}.
