    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.

    Shapes of Simple Molecules - Part 1 (Screencast)

    Shapes of Simple Molecules - Part 1 (Screencast)

    In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.

    Gas Volume vs. Pressure (Boyle's Law)

    Gas Volume vs. Pressure (Boyle's Law)

    Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.
