Heat Capacity question

  1. Sep 28, 2004 #1
    Find the molar heat capacity of the monoatomic ideal gas in the constant gravitational field. (clue: find the average potential energy as a function of temperature using the barometric formula.)

    could someone please help me out?

    how does the constant gravitational field effect the dQ/dT? Perhaps it means that there is a certain pressure and volume. if p=f/a , v=ah, so pv=fh mgh=fh so pv=mgh
    if total enthalpy H= PdV or dPV, so perhaps dQ/dT=PdV/dT. what is the total potential energy of an ideal gas??
