According to kinetic molecular theory, what happens at absolute zero?

The statement that at absolute zero, all molecular motion ceases aligns perfectly with the principles of kinetic molecular theory. Absolute zero, defined as 0 Kelvin or -273.15 degrees Celsius, represents the theoretical temperature at which particles possess the minimum possible amount of thermal energy.

At this temperature, the kinetic energy of molecules is minimized, leading to a complete halt in their motion. In essence, this means that the molecules would not move or vibrate, achieving a state of maximum order and no thermal energy.

This concept is significant in thermodynamics and helps us understand temperature and the behavior of gases, solids, and liquids. As the temperature increases from absolute zero, molecular motion resumes and energy begins to be introduced into the system. While the notion of inert gases might imply a lack of chemical reactivity, this does not refer to the motion at absolute zero. Similarly, the release of energy does not accurately encapsulate the fundamental behavior of molecules at this unique temperature.
