Jerry E. Allen, a 15 year old male from the Internet asks on May 2, 2000,Is it possible to freeze water in a vacuum? Is there a chart that shows water temperature vs. pressure/vacuum?

No. In a vacuum, there's no matter. So there's nothing to freeze. Vacuum means nothing (or nearly nothing) is there. At near vacuum, the water would probably be a gas, unless it was really cold. Here is a chart showing the phase of water at various temperatures and pressures.
I have seen it done before. Place a container of water in a chamber and pull vacuum on it. The water will slowly change from liquid state to gas state. It takes energy to change states, so as it changes states and releases energy (or heat), the water eventually freezes into a block of ice.
