1. N identical particles of mass m is confined to move only about a surface of area A, and thus can be considered as a “two-dimensional gas.” In the classical limit what is the single particle partition function of one of the particles in this ideal two-dimensional gas? What is the partition function of the N particle gas? What is the mean thermal energy of this gas, and what is the entropy of this gas?
