Gas density

  1. Jan 24, 2008 #1
    I am in high school chemistry and we are learning about gases. Do gases expand indefinitely? Or at least until the gas is evenly distributed throughout all the other gases that are present?

    That's what I understand happens...

    PV=nRT --> V=nRT/P

    If pressure of the expanse were essentially 0 compared to the gas in question, you'd get infinity.
    It's called Diffusion.

    The article on the Ideal Gas Law is interesting, and should provide some insight.
