Unformatted text preview: the temperature reaches the critical temperature for nitrogen. If the gas were ideal, how much work would be done on the gas during the compression? If the gas were nitrogen, how much work would be done? How significant is the difference in the values? ( 6 points ) 2) (15 points) A 15 liter rigid vessel contains 10 kg of water (liquid and vapor) at 30C. If the vessel is heated, will the liquid level rise or fall? What if the vessel contains 1 kg of water instead of 10 kg? In the two cases, what is the temperature when one of the phases just disappears? Hint: consider the T-V projection of the water equation of state and the specific volumes in the two conditions relative to the volume at the critical point....
