Thermodynamic temperature and exchange energy in collisions. "Figure 1" below shows translational motion in gases; "" below shows translational motion in solids. Thermodynamic temperature's null point, absolute zero, is the temperature at which the particle constituents of matter are as close as possible to complete rest; that is, they have minimal motion, retaining only quantum mechanical motion. Zero kinetic energy remains in a substance at absolute zero (see "Thermal energy at absolute zero", below). Throughout the scientific world where measurements are made in SI units, thermodynamic temperature is measured in kelvins (symbol: K). Many engineering fields in the U.S. however, measure thermodynamic
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,
