Freezing a soda will cause its top and bottom to bulge

    1. The problem statement, all variables and given/known data
    No data


    2. Relevant equations

    No equations. Theory


    3. The attempt at a solution
    Freezing the soda can will makes the soda can contract, thus increasing the pressure of the soda. P=F/a.
    However, as pressure had increase, to the air particles in the soda can will have more frequent collision and cause the bulging to reduce the increased pressure?

    Am i on the right track?
    Thx in advance for the input!~ :D

    No, the can does not contract measurably. The water (soda) freezes, and ice is less dense than water (that's why ice cubes float). The ice takes up more volume than the unfrozen water did, forcing the can to bulge out.

    BTW, questions like this would be more appropriate to the Intro Physics forum.
