3. An air-filled piston - cylinder assembly starts at p1 = 30 lbf/in', Ti = 540\deg F, = andV, 4 ft. The air undergoes a process to a final state of p2 = 20 lbf/in' and 2 = 4.5 ft. During this process, 1 Btu of work is done on the air by the paddle wheel, and 12 Btu of heat is added to the air. Remember to pay attention to your units!(a) Calculate the temperature at state 2 in \deg R. (b) Determine the energy transfer by work from the air to the piston during this process.
