Boltzmann Equation for Entropy:
5 posts • Page 1 of 1
in class it was said that the third law of thermodynamics says that the limit of S as the temperature approaches 0 Kelvin equals 0. What that says is that the entropy at 0 Kelvin is 0, so it is perfectly ordered material
Also, absolute zero is a theoretical concept. It may not be achieved experimentally. This is because from the second law of thermodynamics, we know that heat will spontaneously move from a warmer body to a cooler body, so the object that one tries to cool to absolute zero will try to take in heat from its surroundings.
