    Avogadro's Law:  If you've got two gases under the same conditions of temperature, pressure, and volume, they've got the same number of particles (atoms or molecules).  This law only works for ideal gases, none of which actually exist. 
    Boyle's Law:  The volume of a gas at constant temperature varies inversely with pressure.  In other words, if you put big pressure on something, it gets small. 
    Charles' Law:  The volume of a gas at constant pressure is directly proportional to the temperature.  In other words, if you heat something up, it gets big. 
    Dalton's law of partial pressures:  The total pressure in a mixture of gases is equal to the sums of the partial pressures of all the gases put together.
    Vapor Pressure: The pressure of the vapor over a liquid at equilibrium in a closed container.
    Elastic Collision: No energy is lost from one particle to another and the total kinetic energy is the same.
    Absolute Zero:  The state at which there is no movement of a substances particles.
    Bar: A unit of pressure equal to 100 kilopascals.
    Gas Constant: A physical constant which is featured in a large number of equations in the physical sciences.
    Real Gas: A gas that does not behave completely according to the assumptions of the Kinetic Molecular Theory.

    absorption:  When something is soaked up by another.  For example, water is absorbed by a sponge.

    bond energy:  The energy it takes to break one mole of a chemical compound into its constituent atoms
    chain reaction:  A reaction in which the products from one step of the reaction provide the reagents for the next
    colloid:  When little tiny particles of stuff are permanently suspended in a liquid
    electrolysis:  When electricity is used to break apart a chemical compound.  The most familiar example of this is the electrolysis of water, in which electricity is used to break water molecules into hydrogen and oxygen gases.
    emulsion:  When small drops of liquid are suspended in another.  An example is salad dressing in which small drops of oil are suspended in vinegar.
    endothermic:  An endothermic process absorbs energy
    energy:  Energy is something in a system that allows the system to either to do work or give off heat
    equilibrium:  When the forward rate of a reversible reaction is the same as the reverse rate.  When a system reaches equilibrium, it appears as if nothing is happening because the concentrations of each chemical remain constant, but the reaction is still occurring in either direction
    exothermic:  When a process gives off energy
