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!
