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 = 300 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 Tᵦ 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.Tₐ, Tᵦ, and Q/nₐ, if P(final) = 1.25 atm.
