PROBLEM: One insulated rigid tank contains 1 kg of carbon dioxide CO2 at 3 bar and 150℃, while a second one contains 0.5kg carbon dioxide at 1.5 bar and 50℃. A pipe and a closed valve connect the two tanks. Once the valve opens, the gas achieves a new equilibrium state. The heat transfer with the surroundings during this process is assumed negligible. Question: (a) Determine the final equilibrium temperature and pressure of the gas. (b) Determine the entropy change of the gas due to this process.

Question
PROBLEM:
One insulated rigid tank contains 1 kg of carbon dioxide CO2 at 3 bar and 150℃, while a
second one contains 0.5kg carbon dioxide at 1.5 bar and 50℃. A pipe and a closed valve
connect the two tanks. Once the valve opens, the gas achieves a new equilibrium state. The
heat transfer with the surroundings during this process is assumed negligible.
Question:
(a) Determine the final equilibrium temperature and pressure of the gas.
(b) Determine the entropy change of the gas due to this process.
