Homework Help: Heat Capacity at Constant Pressure

  1. Feb 3, 2014 #1
    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!
