PROBLEM #3. [30 POINTS! Two tanks are connected by a valve. One tank contains 2 kg of carbon monoxide gas at 77°C and 0.7 bars. The other tank holds 8 kg of the same gas at 27°C and 1.2 bars The valve is opened and the gases are allowed to mix. The final equilibrium temperature is 42°C. Using the ideal gas model, determine the final equilibrium pressure, in bars. Solution:

Nitrogen in a rigid, insulated tank with a volume of 15m^3 is initially at a pressure of 70kPa and a temperature of 0°C. An electric component inside the tank draws 1 A at 120V. The component is energized for 25 minutes and then shut off, and the nitrogen reaches equilibrium. Determine the final temperature and the final pressure of nitrogen, the entropy change of the nitrogen the entropy change of the surrounding T= 25°C and the total entropy change.
