Ga rigid, well-insulated tank is connected to two valves. one valve goes to a steam line that has steam at 1000 kpa and 600k, and the other to a vacuum pump. both valves are initially closed. than the valve to the vacuum pump is opened, the tanks evacuated, and the valve is closed. next the valve to the steam line is opened so that the steam enters the evacuated tank very slowly until the pressure in the tank equals the pressure in the steam line. calculate the final temperature of steam in the tank.
