Volume pressure temperature

    can someone explain the the relationship these have to each other? i know that they are either proportional or inverse proportional but i dont know which ones are. Thanks

    For a given amount of a gas in a container, PV/T stays constant.

    Try leaving any one thing alone and change one thing, and you can see what happens to the third thing; for example, leave T alone, decrease V, then P must increase. Does it make sense? Does squeezing a gas into a smaller container make its pressure go up? Check.

    Why it's dangerous to throw an aerosol can into a campfire. Leave V alone, and increase T, so then P must increase. Kaboom!
