    It's because of the change in temperature which causes a change in pressure, volume or both. This expansion of the volume and the change in the pressure are greater than what the container can retain, hence the explosion.

    The technical formula is

    (P1*V1)/T1 = (P2*V2)/T2


    P = Pressure
    V = Volume
    T = Temperature


    The change in the temperature causes a change in the pressure and volume which causes the can or container to explode.

    • Incorrect. Formula cited describes behavior of gases, not of water-based liquid freezing to solid.

    • For once, I have to agree with Bob ... your formula would lead to the can contracting, rather than exploding.

    • In this equation, as T falls, either P or V or both would have to decrease, not increase.

    • This formula applies to gas, not liquid.
