A closed, nonconducting, horizontal cylinder is fitted with a nonconducting, friction* less, flouting piston which divides the cylinder into Sections A and B. The two sections contain equal masses of air, initially at the same conditions. T1 = 300 K and P1 = l(atm). An electrical heating element in Section A is activated, and the air temperatures slow ly increase; TA in Section A because of heat transfer, and TB in Section B because of adiabatic compression by the slowly moving piston. Treat air as an ideal gas with CP = 7/2 R. and let nA be the number of moles of air in Section A. For the process as described, evaluate one of the following sets of quantities:
(a) TA, TB. and Q/nA, if P(final) = 1.25(atm).
(b) TB, Q/nA, and P(final), if TA = 425 K.
(c) TA, Q/nA, and P(final), TB = 325 K.
(d) TA, TB, and P(final), if Q/nA = , - 3 kJ mol-1.
