Cold refers to the condition or subjective perception of having low temperature. A cold body is often described as the opposite of hot, or as having less heat, although the latter use of "heat" would be incorrect in the context of physics, as heat refers to the transfer of energy between bodies, which do not "have" heat themselves.

A lower bound to temperature is the absolute zero, defined as 0 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to −273.15 °C on the Celsius scale, −459.67 °F on the Fahrenheit scale, and 0 °R on the Rankine scale.

Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in this classical sense. The object would be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because of the uncertainty principle.

He also briefly appeared in the 1989 Wes Craven film Shocker. Singer played with Olivia Newton-John in the music video for Culture Shock.
