Those with very cold temperatures, can you help?

post #1 of 15
Thread Starter 
I read somewhere that very hot or boiling water, when thrown into really, really cold air (near zero temperatures and below), will almost immediately turn into ice crystals but cool water won't.

Can anyone confirm this? We are in the middle of summer Down Under and the temperatures here in Perth never really get that cold anyway. If you do try it, don't burn yourself!

I tried this experiment a few years ago, and it did work!!! The air has to be really dry in order for it to work.

My s/o says this happens because hot water molecules are broken and up and less formed than the molecules in cool water, which have already begun forming the molecule bonds (latticues) to make ice. Since the hot water doesn't have them, the molecules form up much quicker.

Here's a video of the effect you discribe.

yep it does work. I discovered it in alaska when I threw out some hot water in the middle of winter- also tears (which are hot) will freeze on your cheeks

I've seen the tears freezing thing. We had some realllly cold winters in upstate NY when I was about 10-11. One of my friends was late getting to the bus so she was running. It was so cold and windy her eyes teared, and it froze to her cheek.

One time, I seen on the news, they were showing how cold it was, and the weather man poured his coffee out, and it froze. lol.

That's how you know it's cold.

Yes, that's one way to tell that it's cold.

Yeah, once I took a shower and then a little while later went outside, and my hair froze since it was still dripping wet and warm. Stupid move, going outside into freezing temps with wet hair- but I had to get the paper!!

My husband said that is how the ski slopes make snow. I think it's pretty cool!

I used to shower in the a.m. and then walk to school. Any part of my hair that was covered would freeze. If you brushed it, snow would come out! Though it's not supposed to be could for your hair to do that. I also hate it when your boogers freeze! That's also a calvin & hobbes cartoon.

I've had both tears and breathing air freeze on my face, but I've never heard of the boiling water thing. Interesting.

I always put hot water in ice cube trays, because it freezes faster than cold water.

I've done this in the past. It works !

All I know is I will put warm foods either out in the garage or outside the back door of the garage to cool during the winter months and they do so quite quickly!!
