Determine the phase or phases in a system consisting of H2O at the following conditions and sketch P-v and T-v diagrams showing the locations of each state:
(a) p =10 bar, T = 179.9 oC
(b) T = 100 oC, p = 0.5 bar
(c) T = 20 oC, p = 50 bar
(d) p = 1 bar, T = -6 oC
(e) p =100 lbf/in.2, T = 327.86 oF
(f) T = 212 oF, p = 10 lbf/in.2
(g) T = 70 oF, p = 20 lbf/in.2
(h) p = 14.7 lbf/in.2, T = 20 oF
