A cylindrical vessel with rigid adiabatic walls is separated into two parts by a frictionless adiabatic piston. Each part contains 40 L of an ideal monatomic gas with CV,m = 3R/2. Initially, Ti = 280 K and Pi = 170 kPa in each part. Heat is slowly introduced into the left part using an electrical heater until the piston has moved sufficiently to the right to result in a final pressure Pf = 4.20 bar in the right section. Consider the compression of the right section to be a reversible process.
What is the work done on the right section? w = 4446.30J
What is the final temperature of the right section? T = 402.046K
What is the final temperature of the left section? T = 981.481K
How much heat flowed into the left section? q = J
I can solve the first three by myself but when I use q=delta U-w with delta U=n*Cv,m*(Tf-Ti) , it doesn't work at all

[2 ideal gas, thermodynamics process] A cylinder closed at both ends equipped with insulating (adiabatic) walls, and is divided into two parts with a frictionless, insulating, movable piston. The gases on both sides are initially at equilibrium with identical pressure, volume, and temperature (P,:V0:10). The gas is ideal with Cv-3R/2 and Cp/Cv-5/3. By means of a heating coil in the gas on the left hand side, heat is slowly supplied to the gas on the left until the pressure reaches...
