Suppose that after the final process in Fig. 12.22 (Exercise 10), the pressure of the gas is decreased isometrically from 1.0 x 105 Pa to 0.70 x 105Pa, and then the gas is compressed isobarically from 1.0 m3 to 0.80 m3. What is the total work done in all of these processes, including 1 through 5?
In exercise A fixed quantity of gas undergoes the reversible changes illustrated in the p€“V diagram in Fig. 12.22. How much work is done in each process?
