Determine entropy change from initial state to final state
A constant-volume tank contains 10 lbm of ammonia initially at 30 lbf/in^2 and 80(deg)F (539.67(deg)R). The ammonia is then cooled until its pressure drops to 10 lbf/in^2. Determine its entropy change from the initial state to the final state.
