Explain an isolated chamber with rigid walls is divided into two equal compartments, one containing steam at 10bar and 3700C as well as the other evacuated. A valve between the compartments is opened to allow steam to pass from one chamber to the other.
Subsequent to the pressures but not the temperature in the two chambers have equalized, the valve is closed, isolating the two systems. Explain what the temperature is and pressure in each cylinder? Steam isn't an ideal gas under the conditions here
