oooh, on brainiacs on tv, there was this part where the crazy guy, ya know the one, hes crazy, said that if you get ice cube trays, fill one with hot water, and the other with cold water.. That the hot water one freezes first

Anyone know why?? Is the crazy guy high on Turkeys? I dont know what to believe!

Aaaanyway.... Thats freaky, so im gunna try that now.

Wish me luck... And ... STAND BACK...

If you put cold coffee (In a mug) in a bowl and surround it with ice, then put it in a microwave, the coffee doesn't heat up and the ice doesn't melt

Are you for real?!!? [or in the words of tanny: R u 4 shizzle!?]

Wow, That doesnt make any sense.. Freaky.. Interesting

Anyone else know any weird facts? Be it Microwaving, Heating/Cooling up... Kitchen stuff, i guess..

Yeah, saw it on TV a while ago... Although, I can't remember if that's it. It might be if you put hot ice in a mug and surround it with hot coffee, the ice cools down and the coffee heats up

In order for water to be supercooled, it needs to be in a very clean and "smooth" container and it needs to be quite pure:

EXACTLY the same as superheating. Except in a microwave, of course

I still can't believe you watch Brainiacs.

That's odd. I'm sure Newton's law of cooling gets blown out of the water.

We JUST covered this in science yesterday.
Warm water evaporates faster, which cools the rest of the water really fast. The temperature of the hot water just plunges straight down due to evaporative cooling

Basic Chemistry Big

Chemical reactions or phase changes either absorb or give off energy lol.

Well... No, that's not really an explanation in this case.

Both are completely water before and after freezing, so they're both changes in phase rather than endothermic or exothermic reactions. The hot water has a higher energy level to begin with, and so must release more energy in order to become a solid. Inks' explanation certainly sounds plausible, so I'll believe that.

It was an add-on to Inks's explanation
