Temperature the International System of Units, it has subsequently been redefined in terms of the equivalent fixing points on the Kelvin scale, and so that a temperature increment of one degree Celsius is the same as an increment of one kelvin, though they differ by an additive offset of 273.15. The United States commonly uses the Fahrenheit scale, on which water freezes at and boils at at sea-level atmospheric pressure. Many scientific measurements use the Kelvin temperature scale (unit symbol: K), named in honor of the Scots-Irish physicist who first defined it. It is a thermodynamic or absolute temperature scale. Its
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,
