1. For an irreversible process for one mole of monatomic ideal gas in a piston-cylinder system with heat-conductive walls that goes from State 1 (p = 4.0 atm, V = 4.0 L) to State 2 (p = 4.0 atm, V = 9.0 L): (A) (B) Calculate the change in internal energy for the system for this process. Calculate the change in entropy for the system for this process.
