smart people plz

i have a question.

you have hot water, then you have cold water. which will freeze faster?

is it obviously the cold water, because water goes from hot to warm to cold to freezing, or is there some unknown factor that you might not know about that would lead to a conclusion of hot water freezing faster?

im doing an experiment.

The answer you seek..........
Can hot water freeze faster than cold water?

Have a good one!:jointsmile:

Aha!!! You would think. But look at this which says HOT water freezes faster than COLD.Can hot water freeze faster than cold water?
From the University of California.
Damn... P4B beat me to it! By seconds! Foiled again!;)

thanks guys! saved me from a lot of experimentation.

i probably should still do it so i can record all the proper data and findings for my professor..but this might do. heh

IAP isn't the only one with Superpowers! LOL

If you do it post your results.......I'd be VERY interested.:thumbsup:

im actually still going to do it.

the syllabus for the experiment calls for 8 uniform containers of cold water and the same thing, substitute cold for hot.

pop them in the freezer and check back every ten minutes, making note of any crystallization or any other changes you might find. it could be anything..crystal structure, water level height in container, whatever.

in the end you talk about temperature and molecular motion, hydrogen bonds, etc. this really is something out of jr high, and im suprised at my level in college were doing such an experiment, but maybe im just not giving it enough credit..because theres A LOT you have to get exactly correct, or your paper can be shot down easily.

but im definately thinking it has something to do with bonds and how they form. i need to find out just whats going on in that hot water after its in the freezer. like molecularily.

What if you didn't have a freezer? Or are you doing this during your lab time?
