Consider a sample of perfect gas (0.10 mol) held inside a cylinder by a piston such that the volume is 1.25 dm3. The external pressure is constant at 1.00 bar and the cylinder rests in a bath at constant temperature 300 K. The gas expands when the piston is released. Calculate i) The volume of the gas when the expansion is complete. ii) The heat absorbed by the gas during expansion. iii) Total change in entropy.

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.
