SUMMARY
The discussion focuses on deriving a constant quantity involving pressure (P) and volume (V) during a reversible adiabatic transformation of blackbody radiation, using the equations of state E/V=aT^(4) and P=(1/3)(E/V). The approach begins with the fundamental thermodynamic relation dE=TdS-PdV, simplifying it for adiabatic processes where dS=0. The suggested method involves substituting dE with -P dV to facilitate the derivation.
