Scientists offer public $1,600 to crack cold case.... Crack the ICE
Why does hot water freeze faster than cold water?
Aristotle agonized over it fruitlessly in the fourth century BC
Another Bacon, Francis, wrote in his 1620 Novum Organum, that "slightly tepid water freezes more easily than that which is utterly cold" but could not explain why
Descartes was defeated by it in the 17th century AD
Even perplexed 20th and 21st century scientists and intellectuals along with King Black have swarmed over it without result.
Now we scientists and smart ones come to you all to help figure it out...

This might be ridiculous, but if the molecules are spinning faster in the warm water, when met with cold, they will slow faster. However, if the water is already cold, the molecules won't have to slow down as much, so they will slow down slower. Thus, the molecules in the warm water slow down faster and freezes first. Just a theory! Also, convection currents differ between warm water and cold. This may help the warm water cool faster. I seen that to but its not an exact answer as to why it happens as when you get to around the halfway point it states after summing it up that there still is no real explanation as to why it happens. Hence the reason scientists of today are offering 1600 smackarooos to anyone who can figure it out. Think of the water molecules as cars driving. In hot water, the molecules move very rapidly, while in cold water, they move very slow. Now view the freezing temperature as the brake system. Going from a higher temp. to a freezing temp. will cause the molecules to react like a speeding car slamming on it's brakes. The molecules slow down at a faster rate than as a moderate moving car, gently pressing the brakes. Also, the byproduct of heat is already being released for the hot water, so using the energy to slow down the molecules comes naturally. For the cold water, energy that must be used to slow down the molecules is also warming the cold water (very minuscule, however still there). Just my thoughts, comment if you please. |
