14 grams of water at 298 K are placed in an evacuated steel container whose volume is 10 L. If we assume that the volume of the liquid water may be ignored relative to the volume of the container, answer each of the following question:
(a) when equilibrium is attained, how much liquid water is left in the container?
(b) repeat part (a) if the temperature is 320 K.
(c) repeat part (a) if the temperature is 340 K.
(d) repeat part (a) if the temperature is 373 K.
(e) repeat part (a) if the temperature is 390 K.
(f) using the results of parts (a)-(e), make a graph of the mass of liquid water left as a function of temperature.
(g) what is the minimum temperature to which the container must be heated to put all of the water into the vapor phase?
(h) compute the pressure inside the container when the temperature is 420 K, 450 K, 475 K, and 500 K.
(i) plot the pressure inside the container as a function of temperature over the range from 298 K to 500 K.
Assume the molar enthalpy of vaporization of water is 44.00 kJ mol-1 and that the normal boiling point of water is 373.15 K.
