Boltzmann Equation for Entropy:
3 posts • Page 1 of 1
Can someone clarify what the Second and Third Law of Thermodynamics are, and how they are different? They both have to do with entropy, so I think I just need to see the different applications of both! Thanks!
The second law of thermodynamics states that the entropy of an isolated system increases from any spontaneous change. An example of this would be how the spontaneous cooling of hot metal in a cold environment causes an increase in entropy since the heat spreads to the surroundings. The third law of thermodynamics states that the entropy of a system approaches 0 as the absolute temperature approaches 0. This concept is usually used to analyze the response of materials to temperature changes.
