Three of the special ideal-gas processes involve a changing volume: isobaric, isothermal, and adiabatic. Consider three different compressions, all starting at the same initial state (with initial pressure of Pị, initial temperature Ti, and initial volume Vi). All three processes involve compressing the gas by half, so the final volume in each case is V? = { vi. A. a. Determine whether the change in temperature AT for each process is positive, negative or zero. B.
b. Based on your answer above, rank the final pressure of the gas in each process (Pf isobaric, Pf, isothermal, and Pf, adiabatic) from largest to smallest. P C.
c. Sketch the three processes on the PV diagram . All of them should start at the same state on the diagram, but end at different states. Label each process on your diagram
D. Use the area under each curve to rank the work done on the gas in each process, from largest to smallest.
E. Determine whether the heat flow to the gas is positive, negative, or zero for each process
