... (c) (8 points) From the properties of a 2D equilibrium photon gas, calculate the adiabatic exponent γ that determines how the pressure P and two-dimensional “volume” A (area) are related, P Aγ = constant, during an adiabatic (constant-entropy) process of the gas. For a 3D photon gas, one has P V γ = ...

... The potential energy of a system is equal to the negative work done by internal forces on the particles in the system. It is related, in general, to the separation of the particles. The greater the separation, the greater the potential energy. The less the separation, the less the potential energy. ...
