    Hot water is heavier than cold water, true or false?

    Question #59964. Asked by trimtrivia.

    picqero

    Water, like most other materials, expands when heated so cold water is denser than hot water and is therefore heavier, assuming the quantities are identical of course. This is why the top of a water heated radiator warms up before the bottom; the warmer water 'floats' on top of the colder water. The same effect is sometimes very evident while swimming in a calm sea or lake, the warmer water being close to the surface.
    Simply heating any quantity of water, however, will not increase or decrease its weight.

    Water in its normal state will decrease in density as you increase its temperature. Example, water at 4 degrees Celsius has a density of .99998 g/ml, and at 30 degrees Celsius has a density of 0.9957 g/ml. However there exists the possibility for water to be super cooled. In nature this usually only happens in clouds. But if you cooled it quick enough you could super cool it to -45 degrees Celsius before it froze. Water that is super cooled decreases in density the colder you get. Water that is -30 degrees has a density of 0.9839 g/ml.
