Question

Ten moles of a gas are placed in a rigid container. Initially the gas is at P=0.5 bar and T= 300 K and the container is also at T= 300K. The container is placed in a furnace,

where its surroundings are at a constant T = 600K. The container is left in the furnace until both the container and the gas inside it reach equilibrium with the surroundings.

The gas has a constant heat capacity of Cv = 2.5 R. The container itself has a mass of 10kg (not including the mass of the gas inside) and a heat capacity of Cv=1.5 J/gK.

Find: heat added to the gas, heat added to the container, change in entropy of the gas, change in entropy of universe. Finally, in your own words frame this problem in terms of

reversibility or irreversibility.
