Question
A closed, nonconducting, horizontal cylinder is fitted with a nonconducting, frictionless. floating piston which divides the cylinder into Sections A and B. The two sections contain equal masses of air, initially at the same conditions. T1 = 348 K and P1 = 1 atm. An electrical heating element in Section A is activated, and the air temperatures slowly 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 the following sets of quantities:
TB, Q/nA, and P(final), if TA = 465 K.
TA, Q/nA, and P(final), if TB = 345 K.
TA, TB, and P(final), if Q/nA = 5 kJ mol-1.
