    Vapor Pressure

    Vapor Pressure

    Vapor pressure is the pressure exerted by molecules in the gas phase in equilibrium with a liquid or a solid. Two examples are used to illustrate vapor pressure: the drying of clothes and the evaporation of ice.

    The Effect of Temperature on the Vapor Pressure of a Liquid

    The Effect of Temperature on the Vapor Pressure of a Liquid

    Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.

    Standard Molar Volume

    Standard Molar Volume

    Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.
