QUIZ 1. What most affects the vapor pressure of a liquid? a. Its polarity b. Its temperature c. Its volume d. Its melting point Answer: b. The temperature of a liquid will increase the vapor pressure of a liquid. 2. What is the point at which a liquid is in equilibrium with its vapor at a partial pressure of 760 torr called? a. Critical point b. Vapor pressure c. Normal boiling point d. Freezing point Answer: c. The normal boiling point is the point at which a liquid is in equilibrium with its vapor at 760 torr or one atmosphere of partial pressure. 3. What is not an equivalent number at 100 degrees and 760 torr? a. Condensation point b. Boiling point c. Dew point d. Critical point Answer: d. Each of these is the same value under the conditions of 100 degrees and 760 torr with the exception of the critical point where there is no possibility to have the gas become liquid.
