A cylinder is closed at both ends and has insulating walls. It is divided into two compartments by an insulating piston that is perpendicular to the axis of the cylinder as shown in Figure a. Each compartment contains 1.00 mol of oxygen that behaves as an ideal gas with Gamma = 1.40. Initially, the two compartments have equal volumes and their temperatures are T1i=530 K and T2i = 275 K.
