1. Adiabatic Mixing
A rigid insulated tank contains 5 kg of steam at 15 bar, 300 °C. A second tank, also insulated and rigid, contains 15 kg of steam at 8 bar, 500 °C. The two tanks are connected via a pipe and a valve that is initially closed. The valve is opened and the two compartments are allowed to exchange contents. Determine the temperature and pressure at the end state. Is this process reversible? 2. Irreversible Expansion Against Vacuum
A closed insulated cylinder is divided into parts by a piston that is held into place by latches. One compartment is evacuated, the other contains steam at 7.5 bar, 300 °C. The latches are removed and the gas expands to fill the entire volume of the cylinder. When the system reaches equilibrium, its pressure is 1 bar. Determine the final temperature.
