A1-mtank containing air at 10C and 350 kPa is connected through a valve to another tank containing 3 kg of air at 35C and 150 kPa. Now the valve is opened, and the entire system is allowed to reach thermal equilibrium with the surroundings, which are at 20C. Determine the volume of the second tank and the final equilibrium pressure of air. The gas constant of air is R= 0.287 kPa-m3/kg-K. m3 The volume of the second tank is The final equilibrium pressure of air is kPa
