Vapor Pressure Table H Review

As water in a sealed container is cooled from 20C to 10C, its vapor pressure

• decreases

• increases

• remains the same

When the vapor pressure of a liquid is equal to to atmospheric pressure, the liquid will

• freeze

• boil

• melt

• condense

Which sample of water has the lowest vapor pressure?
