You have an initially empty 1 m³ tank that is connected to a giant reservoir of air at P=5 bar and T=298 K. The tank is well insulated. A valve is open, and air begins flowing into the tank. What is the temperature in the tank when the pressure equilibrates?

After your tank equilibrates, the valve is closed. Unfortunately, your tank sprang a leak. What is the temperature if 25% of the air leaves?
