1. The problem statement, all variables and given/known data Calculate Q(in) and Q(out). 2. Relevant equations Specific Heat: Cv = 5/2 R R = 8.314 J/mol K 3. The attempt at a solution For the process C-> A, it is an isothermic process but we are not given temperature. The equation to finding the total work done from C->A is nRT ln (Va/Vc). How do I get T in order to solve for nRT ln (Va/Vc)?
