Phase changes

  1. Jul 24, 2011 #1
    This might be a question with an obvious answer, but i want to make sure.

    During the phase changes from a gas to a liquid and from a liquid to a solid, the gas must give off heat, right... so the air around it gets warmer since the surroundings gain heat?

    Yep! Cooling something down, which is simply removing heat, is how you condense or freeze things. In a freezer or refrigerator the air warms up and is continually cooled back down by the fridge.
