Question #3179

State the follwing - the volume of a gase at 0 kelvin.

Expert's answer

If you use the equation of the state for ideal gas

PV = NkT, formally& follows that if T = 0, PV also should be equal to zero (or V =0 if P= const). But the laws for ideal gases& do not work in such extreme temperature. The gas will no longer be a gas at absolute zero, but rather a solid, and we should use the Heisenberg Uncertainty Principle from Quantum mechanics to describe the states of atoms at such conditions.
