Concept of 3rd Law of Thermodynamics

Postby Milena Aragon 2B » Sun Feb 10, 2019 3:33 pm

Can someone please explain the concept behind the third law and what kind of problems we may encounter where we would need to use it? Thank you.

The concept is that entropy’s theoretical limit is 0 if there is absolute order in a system. We can calculate positional and residual entropy with formulas you learned in class.

What do you mean by absolute order?

Meaning a perfect crystal with no impurities.
