All Laws of Thermodynamics

Postby TanveerDhaliwal3G » Sun Feb 09, 2020 11:25 pm

Should we be able to verbally explain all the laws or is knowing the equations associated with each law what we are expected to know?

I think we have to know what they are at least for calculations. I'm not too sure about concepts.
1st law: delta U = q+w
2nd law: for irreversible process (all real processes), delta S(uni) > 0. (total entropy of surroundings and system increases)
3rd law: for perfect crystal at 0K, deltaS= 0 --> 1 microstate

not sure about the concepts, but I feel like if you know the conceptual side or the actual formula part well, you'll be able to figure out the part you don't know
