Freezing water in an unexpandable container?

  1. Sep 16, 2008 #1
    If you did had a container that was strong enough to resist the expansive forces generated as the water in it freezes, what would happen? (assuming the container is filled completely with water)

    Thanks for any answers in advance, and I hope this post is in the correct place, if not, then sorry!

    Welcome to Physics Forums leakeg!

    If the container really is strong enough, the frozen water would be under a tremendous amount of pressure in order to maintain its original volume.

    thanks for your reply!

    so you're saying the water would freeze? so we would have a compressed solid? or would the ice be a different form of ice? would it freeze at a colder temperature?

    is this even possible in the real world?

    wow that was a lot of questions haha.

    There is something like 7 different types of water ice (the phase diagram of water ice is VERY complicated), which form it freezes into would depend on the temperature and pressure.

    alright, cheers!

    how much do you guys think it would lower the freezing point by?
