I need help with Boyle's law, and Charles' Law... Please help!?

I have a test tomorrow, including Boyle's and Charles' Law. I don't really understand either of them... Can some one explain them a little bit, and tell me the difference between the two? Thanks! :P (by the way, my test is TOMORROW, so I need to know soon!) thanks a bunch!


haha i accidentally made it 1 week, but i need an answer today!!!! short notice, i know, but i need it for tomorrow's test. thanks!

    Boyles Law

    At constant temperature the volume

    occupied by a fixed amount of gas is

    inversely proportional to the pressure

    on the gas



    V=k1/P (where k1 is a proportionality constant)

    (at constant temperatue when the pressure on the gas is increased, the volume of gas occupied is decreased, similarly wen d pressure is decreased the volume increases.)

    in boyles law temperature remains constant and wen pressure of gas increases volume occupied decreases and vice-versa.

    charles law

    in charles law pressure remains constant and wen d temp increases the volume of the gas also increases. wen temp decreases volume decreases.

    "The volume V of a fixed amount of

    gas at constant pressure is

    proportional to the absolute

    temperature, T

    V ~T

    or V=k2 T (k2 is a proportionality constant)

    boyle's law:


    there is an inverse relationship between the pressure and volume of a gas (as one goes up, the other goes down). in normal problems, you will be given three values and have to solve for the unknown

    charles' law:


    there is a direct relationship between the volume of a gas and the temperature (in kelvin).
