A rigid, insulated vessel is divided into two compartments connected by a valve. Initially, one compartment, occupying 1.0 ft², contain air at 50 lb/in², 500°R, and the other, occupying 2.0 ft², is evacuated. The valve is opened and the air is allowed to fill both volumes. Assume the air behaves as an ideal gas and that the final state is in equilibrium. Determine the final temperature of the air, in °R, and the amount of entropy produced, in Btu/ºR

A rigid, insulated vessel is divided into two compartments connected by a valve. Initially, one compartment, occupying 1.0 ft², contains
air at 50 lb/in², 500°R, and the other, occupying 2.0 ft², is evacuated. The valve is opened and the air is allowed to fill both volumes.
Assume the air behaves as an ideal gas and that the final state is in equilibrium.
Determine the final temperature of the air, in °R, and the amount of entropy produced, in Btu/"R
Step 1
Determine the final temperature of the air, in °R.
T+= 500
