Absolute Zero
The theoretical temperature at which molecular motion vanishes
and a body would have no heat energy; the zero point of the
Kelvin and
Rankine temperature scales.
Absolute zero may be interpreted as the temperature at
which the volume of a perfect gas vanishes or, more generally,
as the temperature of the cold source which would render a Carnot
cycle 100 percent efficient. The value of absolute zero is now
estimated to be - 273.15° Celsius, -459.67° Fahrenheit,
0° Kelvin, and 0° Rankine.
