Okay, im doing a science project for school, my topic was on hot water freezing faster than cold water but when i did the experiment the cold water froze faster can you tell me why this would happen?

when you have a freezer that is a bit overfrozen with frost, the hot water ice cube trays will melt into the ice and form a better "conduction" of heat, thus sucking the heat from the hot water at a faster rate than the cold.
If it takes 1 unit of energy to go from 34 degrees F to 33 degrees F (still liquid), then it takes 9 times as much energy sucked out to go through the transition from 33degrees F to 32degrees F (frozen ice). If you get the cube tray to melt into that ice, then it will get through that transition from water to ice much faster.

As I recall, it was that hot water made clearer ice cubes than cold water, not that hot froze faster.

I cannot offer any explanation, but would like to give some additional information for your science project.
Did you know that water is the only liquid that can contract and expand at the same time?
