A 200 L adiabatic container is empty and closed by a stopcock. Ambient air is at 300 K at a pressure of 1 bar. The stopcock is opened to let exactly one mole of air into the container. a) Assuming that the air behaves as an ideal gas, find the temperature and pressure inside the container at equilibrium. b) Find the enthalpy and entropy change of the gas that is inside the container at the end of the process.
