1.Give the phase for the followingstates.
a) CO2 T=267celcius P=0.5
b) Air T=20 celciusP=200kPa
c) NH3 T=170celcius P=600kPa
Label them onto P-v and T-sdiagrams.
2.Give the phase and the missing property of P, T, v and x. Put the values in a table withcolumns P, T, v, and x.
a) R-134a T=-20 celcius, P=150 kPa
b) R-134a P=300 kPa, v=0.072 m3/kg
c)CH4 T=155 K, v=0.04 m3/kg
d) CH4 T=350 K, v=0.25 m3/kg
