6- 1 CHAPTER SIX 6.1 a . AB: Heat liquid - - constant V BC: Evaporate liquid - - increases, system remains at point on vapor - liquid equilibrium curve as long as some liquid is present. C. o V T = 100 CD: Heat vapor - -T increases, V increases . b. Point B : Neglect the variation of the density of liquid water with temperature, so ρ = 1.00 g/mL B and 10 mL V = Point C : H 2 O (v, 100 ° C) 10 mL 1.00 g 1 mol 0.555 mol mL 18.02 g n == 0.555 mol 0.08206 L atm 373 K 17 L 1 atm mol K C CC C C C nRT PV nRT V P =⇒ = = = 6.2 a . mm Hg final P = 243 . Since liquid is still present, the pressure and temperature must lie on the vapor-liquid equilibrium curve, where by definition the pressure is the vapor pressure of the species at the system temperature.
