1. The problem statement, all variables and given/known data A cylinder is closed at both ends and has thermally insulating walls. It is divided into 2 parts (left and right) by a movable, frictionless, thermally insulating piston. There is a heating coil in the left compartment, and there are N molecules of an ideal gas, with heat capacity Cv = 7/2 Nk, in each compartment. Originally, the volume and temperature on each side are V0 and T0. The left side is slowly warmed with the coil until its pressure doubles. Give answers to the following in terms of Nk, T0, and V0, only. What are the final temperature and volume on the right side? 2. Relevant equations PV = NkT 3. The attempt at a solution From the value of Cv I know that the degrees of freedom are 7, so U = (7/2)NkT for each side before the piston moves. Since the piston is thermally insulated does that mean the temperature on the right side won't change? So T = T0? If that's the case then V = V0/2 wouldn't it? Is it that simple or am I completely missing something?
