Consider a gas consisting of N identical, non- interacting particles in a container with volume V. The energy of each particle is quantized, such that it can take on any of the values E, 2E, 3E, ..., where E is a constant. Assume that the particles obey the Fermi- Dirac statistics. a) Derive an expression for the total internal energy of the gas as a function of the number of particles, N, and the volume, V. b) Derive an expression for the chemical potential of the gas as a function of the number of particles, N, and the volume, V. c) Derive an expression for the pressure of the gas as a function of the number of particles, N, and the volume, V. Note: This problem requires knowledge of statistical mechanics and Fermi-Dirac statistics. It is recommended to approach it with a clear understanding of these concepts and relevant equations.
