Absolute Zero

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Absolute zero is the temperature at which all motion within molecules completely stops.  Below absolute zero temperature does not exist.  At this temperature nothing is in motion.  The lowest temperature possible is \(-273.15^\circ\)C, or \(0^\circ\) on the absolute Kekvin scale.  The idea that it is impossible, through any physical process, to lower temperature of a system to zero is known as the Third Law of Thermodynamics.
