Document Summary

H = u + (cid:507)pv(cid:508) = u + (cid:507)p v- pv(cid:508) Q = ncp(tb ta) for u, ncvdt for s. = w/qin = (t2 t1)/t2. I = (2g/2ni) at constant t, p, and ni. I is the chemical potential. (cid:507)d g/t(cid:508)/dt = - h/t2 => gibbs helmholtz. Isentropic and isometric compressions followed by isentropic and isometric expansions. Since q=0, u = -w = -ncv(tb ta) Q = 0 p, v, t are variable. Pv = constant, and tv -1 = constant. = cp/cv = 5/3 for monatomic ideal gas. Work = nrt*ln(vf/vi) = (p2v2 p1v1)/1- . T = 0, u = 0 therefore q = w. H = 0 because h is a function of t. No work done, since w = p v. Q = u + w = ncv(tb ta) + nr(tb ta) Intensive - independent of the quantity of material. [t, p, cp and cv], and all specific and molar properties.
