Using the appropriate tables, determine the change in specific entropy between the specified states, in Btu/lb · °R.

(a) water, p1 = 10 lbf/in.2, saturated vapor; p2 = 500 lbf/in.2, T2 = 700°F.
(b) ammonia, p1 = 140 lbf/in.2, T1 = 160°F; T2 = -10°F, h2 = 100 Btu/lb.
(c) air as an ideal gas, T1 = 80°F, p1 = 1 atm; T2 = 340°F, p = 5 atm.
(d) oxygen as an ideal gas, T1 = T2 = 520°R, p1 = 10 atm, p2 = 9 atm.
