(a) Starting from one of the expressions that follows, find a general expression for the following derivative in terms of no more than T, v, P, Cp, Cv, R . (b) Now find an expression for this derivative for an ideal gas, again in terms of no more than T, v, P, CP, Cv, R du = CydT + T V av dh = CpdT + VT dP at av ds = dT dP at P = +(769). -Pdv ] = (0-1),Jap @] - T-C), +@.. du = Tds Pdv dh = Tds + vdP da = -sdT Pdv dg = -sdT + vdP = dP Cp CP,0 = -TS Co Co,0 = T Sco(72) dv = ds = dT + T dv .
