Lambert Pyrometrie (1779) ii. ii. 29)] Physics the lowest temperature theoretically possible; (originally) that at which there is no heat left in an object, (in later use) that at which molecules possess no kinetic heat energy and no motion other than zero-point motion.Absolute zero is one of the defining points of the Kelvin temperature scale, being made equal to zero; it corresponds to −273.15° Celsius.
