If you look at the table of specific heat values for different metals, they are all so different from one another. The difference is mainly because specific heat is expressed as energy per unit mass. If specific heat were given as energy per mole, the values would be very similar. It is, in fact, this similarity of the molar specific heats of metals, which is the basis for the Law of Dulong and Petit. The law of Dulong and Petit...

At a given temperature, the difference between the specific heats of a diatomic ideal gas and a monatomic gas is partly due to rotational energy of the diatomic molecules. A quantum rigid rotator has energy levels Erot (1) with degeneration given by ħ2 Erot(1) = 1(1+1) g() = 21+1, 1 = 0, 1, 2,... g(0) 21 where I is the moment of inertia.
