E The Carnot cycle, which is a particular example of a thermodynamic cycle, allows determining the efficiency of a "heat-to-work" engine. Clausius used this to find the macroscopic definition of entropy as the heat change of the system at a particular temperature. Th and T are the high and low qh and q for the heats transferred at these temperatures. When plotted in a T-S temperatures and representation, entropy only changes in the processes (steps) where heat is added or removed. However, when plotting the Carnot cycle in the P-V representation it is clear that work is done (on or by) the system in each of the 4 processes of the cycle. a) Give the names of the 2 processes of the Carnot cycle (an engine) in which the surroundings do work on the system. Indicate the condition(s) of the walls for these processes. b) Consider the microscopic, i.e., Boltzmann's, definition of entropy for an ideal gas. Briefly discuss what needs to be satisfied so that there is no change of entropy during a…

5. Consider a lattice gas of N particles distributed cells (with N < V). Suppose that each cell may be either empty or occupied by a single particle. The number of microscopic states of this system will be given by among V! N (V, N) = N! (V – N)! Obtain an expression for the entropy per particle, s = s where v = V/N. From this fundamental equation, obtain an expression for the equation of state p/T. Write an expansion of p/T in terms of the density p = 1/v. Show that the first term of this expansion gives the Boyle law of the ideal gases. Sketch a graph of u/T, where u is the chemical potential, in terms of the density p. What is the behavior of the chemical potential in the limits p → 0 and p → 1?
