Actually, when water enters a vacuum, much of it evaporates rather quickly while that which is left over freezes solid. So you would boil and freeze at the same time.

It seems to me that deteriminism is required for free will, not vice versa. When I think of free will, I think that it is me that makes the decisions, thus I determine my own decisions. If there wasn't any determinism, the decisions would be random. How is that a decision? If you go to the extreme and say no determinism, total randomness, one wouldn't be a sane being. You'd be thrashing around as if you had the largest seisure in the history of man. We all have attitudes, desires, out-looks, and world views that make our decisions OUR decisions as opposed to someone else's. That's how we can get to know one another, by familiarizing with each others regular patterns. So you have to have determinism to have any free will at all. Now some people seem to get upset by the idea that physics/chemistry/biology/etc may determine our personality and such and thus our decisions. They think that if they are a bunch of particles following the laws of physics, then somehow it's physics, and not them, that is making the decisions. But they never stop to consider that maybe those two are one and the same. They are the system of particles obeying the laws of physics. The two are not separate. One's propensities are the result of physics/biology/history/whatever acting in conjunction in an intelligent fashion to make you. So what's the problem?
