1. The problem statement, all variables and given/known data For an ideal gas PV = nRT, n is the number of moles. Show that the heat transfer in an infinitesimal quasistatic process of an ideal gas can be written as: dQ = 1/nR ( C_v * V * dP + C_p * p * dV) 2. Relevant equations First law of thermodynamics: dQ = dE + pdv (dE / dT)_P,V = C_P,V Ideal gas PV = nRT 3. The attempt at a solution I have tried back and forth with these equations but does not get closer..
