- Homework Statement
- A crystalline dielectric solid is at a temperature of 300K. Calculate the contribution of the blackbody radiation to its molar specific heat. Compare it with the classical molar specific heat of 3R.

- Relevant Equations
- Stefan's law, E = σT^4

Specific heat, c = ∂E/∂T

For a body at temperature T, the radiative energy per unit area E depends on 4th power of T. I can obtain expression for specific heat c by differentiating Stefan's law with respect to T. Would it be the correct way of approaching this problem?

Or do I need to employ certain models from Solid State Physics such as Drude's/Einstein's/Debye's model?

In either cases, I am provided with only the temperature T and no other constants. How should I attempt such a problem?
