Absolute Zero is a term referred to the theoretical point when entropy reaches its minimum value. In classic kinetic theory, following the thermodynamic laws, molecules should technically not have any kinetic energy (movement) at absolute zero, however recently scientists have shown that this is not the case. Absolute zero is defined as 0K (Kelvin) and is equal to -273.15 degrees celsius. Scientists have yet to reach absolute zero, but have temperatures very close to said point.
