Question

define the third law of thermodynamics

Answer 1

It states that at absolute zero, the entropy of a perfectly crystalline substance is zero.

Answer 2

Answer:

➡️The third law of thermodynamics states that the entropy of a system at absolute zero is a well-defined constant.

➡️This is because a system at zero temperature exists in its ground state, so that its entropy is determined only by the degeneracy of the ground state.

➡️The third law of thermodynamics holds for any system - classical or quantum mechanical.

➡️It basically states that absolute zero (0K or -273.16°C) cannot be reached and that its entropy is zero.
