1. A diatomic ideal gas, at the initial state of T;= 300 K, P; = 1 atm and V;= 10 L is heated at constant volume until P = 10 atm. It then undergoes a reversible isothermal expansion until P = 1 atm. It is then restored to its original state by the extraction of heat at constant pressure. Depict this closed cycle process in a P-V diagram. Calculate w, q, AU and AH for each step, and for the total process. 1. A diatomic ideal gas, at the initial state of T;= 300 K, P; = 1 atm and V;= 10 L is heated at constant volume until P = 10 atm.
