Two moles of an ideal monoatomic gas (CV=20.9JK-1mol-1)are heated from 300K to 350K.The volume of the gas changes from 0.02m3 to 0.2m3.Assuming that the heat capacity remains constant in this temperature change for the system, calculate; i. Entropy change for the system. ii. Entropy change for the surroundings. iii. Entropy change for the universe.
