A vessel containing 2.25 mol of an ideal gas with bar and is in thermal contact with a water bath. Treat the vessel, gas, and water bath as being in thermal equilibrium, initially at 312 K, and as separated by adiabatic walls from the rest of the universe. The vessel, gas, and water bath have an average heat capacity of . The gas is compressed reversibly to . What is the temperature of the system after thermal equilibrium has been established?
