Question

An isolated chamber with rigid walls is divided into two equal compartments, one containing steam at 10 bar and 370oC, and the other evacuated. A valve between the compartments is opened to permit steam to pass from one chamber to the other.
a. After the pressures (but not the temperature) in the two chambers have equalized, the
valve is closed, isolating the two systems. What is the temperature and pressure in each cylinder?
b. If the valve were left open, an equilibrium state would be obtained in which each chamber has the same temperature and pressure. What is this temperature and pressure?
(Note: Steam is not an ideal gas under the conditions here)

Explanation / Answer

b)temperature will be equal to earlier value of 370 pressure will be halved in both chamber and will be equal to 5 bar
