  1. Photons are massless light particles and they do not interact with each other. Consider a gas of N photons in volume V at temperature T. The energy e of a photon is related to its momentum p by the equation e = cp, where c is the speed of light. Find the pressure P and the internal energy E of the photon gas in terms of N, V, T, and k.

' Hint: ? = −??????, where the partition function ? = 4?? ∫(from 0 to infinity) ?? ?^2 * e^-e/kt

Consider a free fermion gas of N particles in a volume V at zero temperature. The total kinetic energy of the gas is U = (3/5)N epsilon-F with epsilon-F = (hbar^2/2m)((3(π^2)N)/V )^ 2/3 . (a) Using the thermodynamic identity show that the pressure of the gas is given by p = − (∂U/∂V )σ,N . (b) Derive an expression of the degenerated-gas pressure and express your final result in terms of U and V .

Laser Cooling of Atoms: In the simplest versions of laser cooling, a gas of atoms can be cooled from room temperature (?300 K) to about 1 × 10-4 K through the absorption of light. The absorbed light transfers momentum to the atoms, thereby slowing down those atoms that are moving in the direction of the incoming laser beam. The following questions refer to a gas of rubidium atoms. (a) The average speed of atoms in the gas phase is directly...

A cylinder of indefinite height contains a frictionless and massless piston. The part of the cylinder above the piston is exposed to the atmosphere with P=1.000 atm. In the bottom of the cylinder are 5.000 kmoles of a liquid that has a boiling point equal to 320.0 K at P=1.000 atm., a heat of vaporization of 2.520 X 107J/kmole, and cp = a+bT-1  for the liquid phase, where a=3.000x104 J/kmole/K and b=2.500x104J/kmole. A. At constant pressure, how much heat is required...

Now consider the warm ionized medium (WIM). In a plasma (ionized gas), particles need not physically collide like billiard balls; they merely need to come close enough for electrical forces to scatter them. The electrical interaction energy between two elementrary charges e at separation r is U(r) = e2/4π0r , (2) where 0 is permittivity of the vacuum. A pair of charged particles will be strongly scattered if they come close enough to make U(r) comparable to their combined kinetic...

2 Equipartition The laws of statistical mechanics lead to a surprising, simple, and useful result — the Equipartition Theorem. In thermal equilibrium, the average energy of every degree of freedom is the same: hEi = 1 /2 kBT. A degree of freedom is a way in which the system can move or store energy. (In this expression and what follows, h· · ·i means the average of the quantity in brackets.) One consequence of this is the physicists’ form of...
