Question:

Repeat Problem 10 for the case when the gas follows the constant pressure path A-E followed by the constant temperature path E-D.
In Problem 10

(a) Find the total work done on the gas if it follows the constant volume path A-B followed by the constant pressure path B-C-D.
(b) Calculate the total change in internal energy of the gas during the entire process and the total heat flow into the gas.
