1. The problem statement, all variables and given/known data A heat engine using a monoatomic gas follows the cycle shown in Figure. Part 2®3 is adiabat, Vi=101 cm3, Vf=668 cm3, Pi=118 kPa, T1=315 K. Find Q for process 1 to 2. Find Ws for process 2 to 3. 2. Relevant equations PV=nRT Q=nCv(delta T) 3. The attempt at a solution I found moles to be 0.0045. But, I don't know where to go from there. I don't know how to find the tempertaure for step 2 and 3. please help the picture is added as an attachment.
