Question

If water gives off heat energy when changing states from a liquid to a solid due to latent heat how does it manage to ever freeze. We are talking about the same type of heat energy that drives hurricanes so this is no small amount of heat ?

Answer 1

Huh??

Giving up heat means it gets COLDER.

Answer 2

Water does give off heat energy when it changes from a liquid to a solid. That is why whatever is around it must be colder than freezing (0 degrees C or 32 degrees F), so it can absorb the heat energy given off.

Take this example: You have a metal rod, at -40C, and you dip it in a bucket of water, at 0C. The water will give off some of its heat energy to the metal as it freezes, so the metal slowly warms up, and both the water and metal reach the same temperature, somewhere between -40C and 0C.

Answer 3

I'll assume that the temperature of the water is uniform throughout and the rate of heat loss is constant for the moment.
As the liquid water cools, it gives off heat to its surroundings. When its temperature cools to 32 degrees, it starts to freeze. While it is freezing, which takes some time, it continues to give off heat (the latent heat). Although the water is still giving off heat, its temperature stays at 32 degrees until it is completely frozen, at which point the temperature of the ice begins to fall below 32. (Assuming that it is still giving off heat.)

Answer 4

The scientific value for the Specific Latent Heat of Fusion for ice is 334 kJ.kg-1, so your value of 319 is not bad at all considering you were not using standard scientific conditions. All your calculations are right also.
