Hehe! I like this selection more than the one you posted before <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />.
I only knew the one about Donald Duck.


I hope we won't have questions about this word in Biology. Talking about a long-answer question!

i find that personaly VERY hard to beleive! <img src="/ubbthreads/images/graemlins/think.gif" alt="" />

Not sure myself. Unless it has something to do with the release of energy. Perhaps there are other properties (gases maybe) present in hot water that's not there in cold.

Still, it's interesting to ponder.

it seems there is still controversy on this topic, but it apparently has been demonstrated: Hot Stuff [New Scientist - Science Q & A]

Idd It was once on a show of "boys and sience" it is called the Mpemba Effect

the diagram that @morbo shows is a interesting one.
Did you notis that the tempatre of the 2 water samples stays the same for a longer time period?
it's about 5000 seconds
it's like the water is freezing at 4 degrees <img src="/ubbthreads/images/graemlins/eek.gif" alt="" />

interesting to know also that that about 4 degress celcius water has the highest density

Water actually does start to freeze at 4 deg C.

Every compound actually has a 'freezing range' of a few degrees. What I find interesting here is that the hot water stays at this temperature for far less time than the cold water. I would call this a 'critical point' in the transition of liquid to solid. I liked the idea of dissolved gasses in the water affecting this. It appears that dissolved oxygen and nitrogen appear to interfere with water crystal formation. As dissolved salts do, but to a lesser extent.

Back to my point. The dissolved gas molecules interfere with ice crystal formation. Therefore the lattice energy (lattice energy is the amount of energy released when a liquid freezes) is higher because the water molecules have to 'kick out' the gasses from their crystal lattice in order to freeze effectively.

Evaporation is a very minor effect when both liquids are at 4 deg C IMO. Convection currents (warm water rising to the surface) are a lot harder to explain however. Convection currents make liquid temperatures non-uniform and therefore an average temperature has to be guessed at. Making the experiment inaccurate.
One of the factors that make liquids so hard to study is that convection is very hard to quantify. This is also true with gasses in some cases. Which is why atmospheric weather conditions are so hard to predict.

Anyway, just some thoughts on the subject. <img src="/ubbthreads/images/graemlins/alien.gif" alt="" /> Chill homes. <img src="/ubbthreads/images/graemlins/silly.gif" alt="" />

It's a big part IMO. Evaporation is important if the temperature of the water sample is high and the container has a large exposed surface area. Evaporation has the effect of removing mass from a high temperature sample, which will then compensate for the greater temperature range. <img src="/ubbthreads/images/graemlins/think.gif" alt="" />

Well yes.... You said it yourself in your post. At a HIGH temperature its very important. 4 degrees celcius is not high however. Evaporation is almost non-existant.

Surface area matters too. You are correct. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />

Yes but the starting temp is 42 degrees. At that time between 42 degrees and 4 degrees a part of the water will be evaporated. I agree with 4 degrees evaporation isn't a factor but it's before the 4 degrees that most of the water evaporates.

Actually a new experiment needs to be performed.

Water of 50 degrees vs water of 4 degrees.

It doesn't seem to matter to me how fast the water evaporated. How you reach the freezing point becomes irrelevant. The point is that the crystallisation temperature is maintained for a MUCH shorter time with the hot water. To me this seems most likely to correlate to the dissolved gas thoerem.

If the idiot allowed the water to evaporate to a point where the volumes differ then its simply like comparing apples and oranges. Of course the water with the lower volume will freeze faster! That is common sense.

From what I gather sealed tube experiments cool faster too. In this evaporation, your largest variable in any liquid cooling curve, is not a factor.

In any scientific experiment, EVERYTHING must be maintained constant while one variable is changed. In this case the size and shape of the containers must be exactly the same. They should be sealed and suspended in the refridgerator to prevent ice-layer contact (with the shelf) and subsequent melting.

That's how I would do it anyway. I beleive it. I just don't accept sloppy scientific methods....

Try your own experiment morbo. Just don't blow anything up! <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />

I think the idiot did that. But Lets just keep it that it is a mixture of the four events combinded <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
