# Absolute Zero

Lowest possible temperature, according to the kinetic theory of gases, attained when a system is at its minimum possible energy, equal to 0 K (-273.15° C and -459.67 F). Temperature is a reflection of molecular energy, thus there must be a point at which no further energy can be extracted from a system. Although it is possible to approach absolute zero, the “third law” of thermodynamics holds that it is impossible to attain absolute zero in a system.
