Ten moles of a gas is placed in a piston-cylinder device, initially at P = 0.1 bar, and its temperature is maintained constant temperature T = 50°C throughout the following process:

∎ The gas is compressed to P = 0.67 bar, at which pressure condensation begins.

∎ At the end of the condensation, the volume is 0.82 L. 490 kJ of heat was removed during the condensation.

∎ The liquid is compressed to P = 13.22 bar and V = 0.80 L, at which point fusion begins

∎ At the end of the conversion of liquid into solid, the volume is 0.73 L. 23 kJ of heat was removed during the fusion.

A. The isothermal compressibility of the liquid phase 

B. The normal boiling point

C. The normal melting point

D. The triple point
