Molar Heat Capacity at Constant Pressure Understanding

  1. Apr 26, 2007 #1
    If I apply 200 J of energy as heat to 4 moles of an ideal gas at constant pressure and the temperature rises by 4 K, then the molar heat capacity at constant pressure will be

    Cp = Q / (n * deltaT) = 200 / (4 x 4) = 12.5 J K mol

    Am I on the right lines here?

    Yes. But it is J / (k mol).
