1. The problem statement, all variables and given/known data A horizontal insulated cylinder contains a frictionless non-conducting piston. On each side of the piston are 54L of the same monatomic ideal gas with the ratio of heap capatities (C_p/C_v) = gamma = 5/3 at 1atm and 273K. Heat is slowly supplied through an inserted heating element(negilible volume) to the gas on the left side of the chamber until the piston compressed the gas on the right side to 7.59atm. What is the temperature on the right side and the left side? 2. Relevant equations 3. The attempt at a solution I recognized that for the right side of the piston, it goes through an adiabatic process for which no heat is involved. I found the volume after compression from the equation PV^gamma = constant. V_f = 16L. Then the temperature after compression is found using PV/T = constant and T_f = 614K. For the left side where heat is added, I'm having trouble finding it out. I know that V_f = 92L. How do I find T_f though?
