A sample of water in the vapor phase (no liquid present) in a flask of constant volume exerts a pressure of 292 mm Hg at 88 C. The flask is slowly cooled.
i) Assuming no condensation, use the Ideal Gas Law to calculate the pressure of the vapor at 76 C; at 70 C.
ii) Will condensation occur at 76 C; at 70 C? Explain.
iii) On the basis of your answers in i) and ii), predict the pressure exerted by the water vapor at 76 C; at 70 C.
