Question

3-75 A 1-m³ tank containing air at 10°C and 350 kPa is connected through a valve to another tank containing 3 kg

of air at 35°C and 150 kPa. Now the valve is opened, and the entire system is allowed to reach thermal equilibrium

with the surroundings, which are at 20°C. Determine the volume of the second tank and the final equilibrium

pressure of air.
