I know an equation sheet is given to us but some stuff are not that important for the upcoming midterm. Can someone tell me what are some if not all of the main equations we need to know for the midterm just so I am not missing anything important?

any equations that involve enthalpy, internal energy, work, entropy, and heat. The ideal gas law as well

Although all the necessary equations are there, you also need to be able to rearrange equations. For example, the formula for heat capacity can be found by rearranging q=nC/\T to get nC = q/T. Some problems, like the one Dr. Lavelle did in lecture, require you to switch around the ideal gas law PV = nRT in various combination.

idk i just try to memorize all of them: entropy and enthalpy for constant vol, pressure, temp and then pv=nrt
