A heat engine is run between two reservoirs at temperatures TH and Tc. One cycle of this engine involves an ideal gas going through two isothermal processes and two adiabatic processes, as shown in the p-V diagram below. All four of these processes are reversible.
Please help me with these questions
a. What is the name given to this cycle, and why is it important?
The volume of the ideal gas at point 1 is V1, etc. By analysing the adiabatic processes, we find that:
V_2/V_1 = V_4/V_3
b. The work done during the isothermal processes is WC (between points 1 and 2) and WH (between points 3 and 4). Find an expression for the fraction WC / WH in terms of TC and TH.
c. Apply the First Law of
d. Use the Second Law of Thermodynamics to explain why no
