Compute the answer of the following problem
Problem- A blackbody photon gas is contained within an evacuated cavity (V = 0.01m3).
Part 1- Calculate the energy that must be supplied to the photon gas if the cavity wall temperature goes from T1 = 300K to T2 = 1500K.
Part 2- Calculate the Cp for the photon gas at T = 1000K
I need assistance to determine the energy that must be supplied in photon.
