A piston-cylinder assembly initially contains 4 mol of substance X in vapor phase at 0.8 bar and 373 K. The vapor is compressed isothermally and reversibly until the first droplet of liquid forms.
Calculate the heat and work interactions with the surroundings if the vapor obeys the virial equation of state with B=? 1887 cm3/mol. The normal boiling temperature and the heat of vaporization of substance X are 354.8 K and 29,750 J/mol, respectively.
