1. The problem statement, all variables and given/known data There is a process that has three phases: isochoric, isobaric and isothermic. How to calculate the transfer of energy as heat(Q) during the isotherm and isobaric process? The temperature and the mass of the gas is known. 2. Relevant equations In isochoric process you can calculate Q using the fact that Q =McΔT. 3. The attempt at a solution I don't know the exact formulas.
