You posted a link to Boyle's law. Did you read it?

(Boyle's law applies to an ideal gas kept at constant temperature.)
Heh. I thought I'd deleted this post. I realized my argument wasn't rigorous.

In diving, we learned Boyle's Law and Charles' Law together - basically showing that volume, temperature and pressure are directly interrelated. Keep any one of them constant, change a second, and the third will vary proportionally (though it may be direct or inverse, depending).

It wasn't until I looked very closely that I realized Boyle's Law is only one piece of the picture. As I said, I thought I'd deleted this post, since it would have just confused things.
