Third Law

Postby Alexandra Carpenter 1G » Thu Feb 01, 2018 10:21 pm

Is the basis of the Third Law of Thermodynamics that perfect crystals have an entropy of 0 as the temperature reaches 0K? Or is there more to it? Thank you!

Yes the third law states that the limit of t approaching 0K of S will be equal to 0 for perfect monatomic crystals

Meaning that the degeneracy of the process is also 1 meaning that we can calculate exactly where molecules are in a perfect crystal.

Because there is no movement at 0K, there is only one possible state (so w=1), which makes entropy equal to 0.
