    I've thought of these so far: Temperature of surroundings, surface area of liquid, volume of liquid.

    Any others, and are these correct?

    Thanks.

    The difference between the temperature of liquid and surroundings..the greater the difference the greater the rate of change in temperature. This is why hot water actually freezes faster than cold water in specific experimental conditions.

    This is true but is not the reason why hot water forms ice faster than cold water. The mechanism is not well understood and research is still taking place on this phenomena. It is true that if you want ice cubes fast it is better to freeze hot water but it is not clear why this should produce ice faster than cooling cold water (which after all, has less energy to extract before freezing)

    Not necessarily true, although it does appear that under certain conditions it can be true.
