Question:
Solve this equation for u to obtain Stephan Boltzmann's law.
In the big-bang theory, the radiation energy which is initially confined in a small region adiabatically expands in a spherically symmetric way. Based on thermodynamic considerations together with results from part (b), find a relation between the temperature and the radius of the volume of radiation. How does the temperature changes as the radiation expands?
