1. The problem statement, all variables and given/known data I have an ideal gas of n=1023 point particles with a constant pressure of P = 3x105 Pa as 200J of heat flows into it. What is the heat capacity at constant pressure, CP? 2. Relevant equations CV = (ΔU + PΔV)/ΔT 3. The attempt at a solution Okay... So I have N, P and Q. I'm not sure if I'm missing something but I have no idea how to even begin finding this without ΔT or ΔV. (Also, the next part of the problem involves finding delta T, which can be found using Q/C, so I'm assuming I shouldn't be finding it in this part of the question.) This is one part of a multiple part question and I can do the rest of them quite easily -- I feel like I'm missing something. Any help is appreciated. Thank you!
