Unformatted text preview: reversible paths a reversible path is an equilibrium path 1 The values of P and T can change, but through-out T = T ext and P = P ext The system does maximum work on the sur-roundings, and the heat transferred to the sys-tem is maximum, i.e. (-w ) max =-w equil path =-w rev -w q max = q equil path = q rev q EXAMPLE: Consider one mole of a monatomic ideal gas contained in a rigid vessel having a vol-ume of one litre at T = 300 K. The gas is heated at constant volume to 400 K. Calculate q, w, E and H for this process. Why isnt q = H ? (Ans: 1247J, 0, 1247J, 2079J) 2...
