Hey guys, I have my final exam in a week for my thermodynamics class. So far this year, things have been sort of roller-coaster-like. I did poorly on my first test because I was caught completely off guard. On my second test, I raised my grade substantially to the point where I was actually pleased with my grade. However, I am stressing out about the final. Both tests this semester have been heavily based on mathematical proof related problems obviously without any numbers. For example, one test question asked to prove that heat will spontaneously flow from a hot einstein solid to a cold einstein solid. My biggest question is what is the best way to go about studying for this final since it will be proof-based. Should I be familiar with a derivation of all usable formulas? Any advice would be greatly appreciated.
