fresh water freezes faster...ps, i gave you best answer on a question

Well, they both take a lot of time! And, I must see the algorithm of (....;)! When both take a lot of time, We should check the one which takes the less time! If both takes the same time, we should choose the one which takes less space (Memory space I mean) But generally, Prefer the 2nd one! I think we should try to use a general code or function in the second choice! If there isn't a general rule, then, I prefer using the 1st one, cause it takes less memory and the lines of codes will be less I suppose...

If you place a glass of hot water in an ice box it will actually freeze faster than a glass of cold water. \n The reason is that the temperature difference makes the water circulate in the warm glass transfering the heat loss evenly through the contents, in cold water the outside freezes first which insulates the inside from heat transfer keeping the center liquid.\n Try it, you'll see.

Water freezes faster.  All sodas contain acid which lower a liquid's freezing point.  The lower the freezing point, the longer it takes something to freeze.

The answer is yes. And I bet you want more of an explanation, which gets a little tricky. It would seem evident that cold water would freeze faster than warm water. But there have been raging debates in scientific circles over whether that's true or false. The fact is a lot of different factors contribute to how fast water freezes, including its beginning temperature.\n    Physicists writing in the journal Scientific American have waded into the fray and have probably come the closest to a satisfactory answer. Quoting Paul G. Hewitt in the book Conceptual Physics, the Scientific American writers believe that hot water will freeze faster than lukewarm water, but not faster than cold water. (Except under certain circumstances.)\n    According to Scientific American, water at 90° C will freeze before water that is 60° C. Below 60° C, however, there is a switch and the cooler water will freeze faster. For example, 30° C water will freeze faster than 60° C water. It has to do with the water evaporation of the hot water immersed in a cold environment. The rate of cooling by evaporation is way higher for hot water than for the cooling of lukewarm water.\n    Now, for those certain circumstances. When you put a pan of cold water and a pan of hot water in a freezer (both pans have equal masses of water), the hot water experiences this rapid evaporation AND freezing from below, which cools water on the bottom of the pan. Because the surface water is already warm or hot, the water at the bottom just sits there instead of rising, getting colder and colder. The water at the top experiences evaporation. The combined effect could make the hot water freeze faster than the cold water.

I've heard that its the boiling water that freezes first. \n\nI think because the water molecules are hot (i.e. they are moving fast) the energy (or heat) will escape (move to equilibrium with other items in the freezer) at a faster rate than the water molecules in colder cup of water. \n\nBut really I'm mostly guessing with my explanation.

it doesnt, however the energy is lost faster in hot water than in cooler water.  The rate at which all water freezes is the same.

Depends on the air temp.... theres days where I have left ice fishing at night.. came back the next day and could poke a hole in the ice with my finger....\n\nIf your in an fish house and have it banked really well, the holes don't freeze as fast.

Do a defrag on your computer...\nClean disk...\nAlso they have RAM chips you can add to your computer which will make it run faster..

Use the highest speed until/unless you have 'write' problems.\nThen I would cut the speed in half and see if it remedies the problem.  But usually it will be something else...

mozilla. It slows your computer less if you're on a limited connection speed and downloads text before graphics, letting you see the page sooner. Plus all the download options and skins are awesome!

macintosh OS ofcourse. Its faster and gives you the best performance, because they are optimixed to give better graphics performance.

What context are you describing (or is that what you are asking)?\n\nHot water will freeze slower than cold water.  In order to freeze the water temperature must be dropped to freezing temperature, and the farther away you are from freezing, the longer it will take to 'bleed' the temperature away by any known method.\n\nI am not aware of any condition where hot water will freeze faster than cold water, assuming the water in both situations is exactly the same (i.e., not water made of different material, or with another chemical in aqueous solution), so if someone can give this example, I would be very curious to see it.\n\nPerhaps there is a situation where you can heat a liquid to convert it into gas, and then from gas directly to solid (frost formation is an example of this).  I am not sure, but this might be one approach to try getting water to go to a solid state faster when the water temperature is initially higher.  The key is you are bypassing the liquid state.\n\nAddendum:\nActually now that I think about it, I have an aswer.  If you have supercooled water, i.e. water that is below freezing, it could stay in that metastable state indefintely.  So here is a case where hot water would cool faster.  The hot water will cool down to freezing and will freeze, while the supercooled water may never turn solid.\n\nAddendum:\nWow, this link that someone below posted is interesting:\nhttp://math.ucr.edu/home/baez/physics/General/hot_water.html\n\nI was going to say that it is impossible, since water at a higher temperature would have to pass through all lower temperatures, but this article pretty much explains it (in that, well, we just don't know).  It has been observed, but there is no explanation that can be agreed upon.\n\nTo be completely pedantic, I note that most of the explanations point to what I would consider to be "experimenter's errors" in the set up of the experiments (if more dissolved gas is in hotter water, than the two water mixtures are certainly not the same, so this is an invalid experiment... if there is a 'hot top', then the experimenter did not start with a homogenious mixture, and that has to be mentioned in the experiment... if the surrounding environment is not the same, then the ambient conditions are changing which not an assumption in a traditional experiment, but rather a source of error... if evaporation is allowed than some quantifiable mass of the water is not turning solid, so this again is invalid).  The only explantation that doesn't result from a poorly set up experiment is supercooling.

AMD..it runs cooler and faster.

7900 GTX is faster then the x1900 by 1.6 gb/s in processing power. Not a whole lot really. \n\nThe x800 xtPE is only faster then the GeForce 7800 GT, the rest of the 7800s are faster.

Possible solutions\n\nClear startup - some prgms would cause freezing at the startup\nRe-install windows\nSwap or change memory sticks.\n\nI am sure this would help u to fix freezing issues.
