Someone told me that if you leave a bucket of warm water out in the cold it will freeze faster than a bucket of cool water. Is this really true or is it a fallacy?Is it true that warm water freezes faster than cold water?
yes, it is true.
because in a warm water, water molecules have more kinetic energy and they are more active. therefore, they give off heat faster
in other hand, a cold water, molecules have less kinetic energy than molecules in warm water. so they are not as active as the warm water molecules and they give off heat slower.Is it true that warm water freezes faster than cold water?
The myth may have arisen from the fact that cold water does absorb heat
faster than hot water. However, once the water gets to a hotter (not yet
boiling) temperature, it absorbs heat at a slower rate, and from that
point it takes just as long to bring the water to a boil as it would if
the water were hot to begin with. And because it takes cold water some
time to reach the temperature of hot water, cold water actually TAKES MUCH
LONGER TO BOIL THAN HOT WATER DOES.
Yes, but not in all circumstances - it has something to do with whether the Mpemba effect takes place.
Go find out! Its quite an simple experiment.
Fill an icecube tray (2 trays one with cold and one with hot) and stick it in your freezer ..or if its cold enough leave it outside .Just make sure to keep checking every hour.
After you have done so let me know and I will post an source why this ';idea'; is partly true. See if you can figure it out.
well pretty much no, not really it is a fallacy
It's true. I refused to believe it too.....but I proved it myself.
True.
YES
wrong.
