gases of which the atmosphere is? composed?

[that is if we neglect variation of pressure of water vapor, and ignore the mountains, and other such minor complications]

Cp atmosphere = Cp of components. What else would you expect?

If I remember right, R=Cp+Cv and Cp is for constant pressure and Cv is for constant volume so that is how you find the two heat capacities. If you know one then you can find the other. Can you get it from here?
