How do you Measure freezing point of water?

Answer 1

To determine the freezing point of a solution, heat must be removed from a sample. A cold sink is needed (a home freezer, a water-ice bath, or salt-water-ice bath is often sufficient). In any event, the cold sink has to be able to absorb enough heat from the sample to cause it to freeze. (This is how a ice cream machine works.) A thermometer is then used to record the decreasing temperature of the sample until it freezes, indicated by a visible change in appearance or State. Plotting the temperature readings will also give a clear indication of the freezing point. There are more sophisticated methods and equipment, but this is the basic method.

Tip: In the case of a liquid solvent, the freezing point is always slightly less than for the pure solvent.

Answer 2

You have a freezer that goes below zero and you keep lowering the temp, slowly, until the water freezes. Then you note that temp.

Answer 3

It is the point at which something freezes, thus when it starts freezing you have found a freezing point.

Answer 4

You measure the freezing point of water with a thermometer.
