SUMMARY
The problem involves black-body radiation expanding adiabatically from an initial temperature T_i to a final temperature T_f in a volume that increases from V to 8V. The correct final temperature factor x is determined to be 0.25, not 1, as photons do not interact with each other, and the expansion does not affect their temperature. The Stefan-Boltzmann Law is essential for understanding the energy and entropy relationships in this context, defined as U=bVT^4 and S=(4/3)bVT^3.
