Physics 157 Written Homework 7 NOTE: You should submit your solution for the following written problem to Canvas as a separate pdf for your written homework 7 assignment. - Question 8: A new heat engine cycle can be described by an adiabatic compression (a b), an isothermal expansion (b c), and an isochoric cooling process (ca), as shown in the graph. The compression ratio is r. For a diatomic ideal gas: Cv = 5R/2, Cp = 7R/2, y = 1.4 Assume the processes are reversible. a) Write down the expressions (not the values) for the heat transferred during each process.
