Absolute zero is defined as the temperature at which a gas theoretically exhibits zero pressure when measured in terms of a fixed mass of an ideal gas. According to the ideal gas law, as the temperature approaches absolute zero, the kinetic energy of the gas particles decreases significantly. Consequently, the movement of these particles slows down and eventually reaches a point where they minimalize their energy and motion completely, resulting in no pressure being exerted.

At absolute zero, which is equivalent to 0 Kelvin, the particles in a gas would ideally be at a standstill, and therefore the gas would exert no pressure. This makes the value of pressure at absolute zero zero, reinforcing the principles of thermodynamics and the behavior of gases under extreme conditions.
