PHYS 258 - Thermal Physics: Assignment 9 Due Monday March 21 Student ID: Full Name: Mark_______/20__ 1. [7] Carnot Cycle Efficiency. a) [4] Prove directly (by calculating the heat absorbed and the heat expelled during one cycle) that a Carnot engine using an ideal gas as a working substance has an efficiency of 1- T C /T H . (At an intermediate step you should get a ratio of two logarithmic terms, which can be simplified using the fact that the two processes on the left and right sides of the Carnot cycle are adiabatic.) T C rejects heat absorbs heat 4 3 2 1 T H V P b) [3] Usually efficiency is calculated using (P,V) diagram (a), but sometimes it is more convenient to do in differently. Plot schematically the Carnot Cycle in (S, T) diagram and calculate efficiency using that diagram.
