question

Ten grams of argon gas at an initial pressure and temperatureof 608kPa, 300°K respectively undergo a changeof state at constant internal energy until the final volumeis three times the initial occupied volume. Assuming idealgas behavior determine the final state (pressure and temperature), and the entropy change of the gas due to the changeof state.
