Temperature for zero temperature, according to the third law of thermodynamics. Nevertheless, a Kelvin temperature does in fact have a definite numerical value that has been arbitrarily chosen by tradition and is dependent on the property of a particular materials; it is simply less arbitrary than relative "degrees" scales such as Celsius and Fahrenheit. Being an absolute scale with one fixed point (zero), there is only one degree of freedom left to arbitrary choice, rather than two as in relative scales. For the Kelvin scale in modern times, this choice of convention is made to be that of setting the gas–liquid–solid
Absolute Zero (film) the atmospheric pressure in the affected zone to drop to zero. The remaining atmosphere would move to this zone and soon Earth would have no gaseous atmosphere, with a surface pressure of zero. None of these events occur in the film, although there is a drastic drop of pressure happening at the end of the film. It is impossible to reach absolute zero naturally, nor would a movement of the poles induce any reduction in Earth temperatures. However, this is explained away in the film as being a previously unknown effect. Furthermore, extremely low temperatures, at or near absolute zero,
