why does hot water freeze before cold water?

Answer 1

the hot water molecule vibrate faster then cold water one, this accelerate the colding process. once the process engaged, the molecule seem to keep higher vibrating speed. Even when reaching them same temp as a colder water started at the same time.

Answer 2

I remember hearing this. For some reason, there is less air in the hot water, and the presence of lots of air molecules in the cold water slows the freezing process--since the freezing point for air is quite low.

Answer 3

Hot water particles are far more spread out than cold. When hot water is frozen, the cold particles fillthe gaps. Cold water has not got as much space, and therefore is harder to freeze

Answer 4

The molecules are farther apart in Hot water and the steam freezes faster do to it is a less dense matter. It is a vapor. A smaller substance.

Answer 5

in case you have a pot of warm water and a pot of chilly water freezing interior the comparable circumstances (i.e. comparable packing containers, comparable freezer, comparable temperature interior the freezer, the two pots of water from the comparable source), the two pots of water are going to chill out on the comparable value. So it somewhat is smart that as a effect the chilly water will freeze first, because of the fact the chilly water substitute into already closer to the freezing element then the nice and comfortable water. in addition, warm water will come to a boil speedier then chilly water, on the grounds it somewhat is closer to the boiling element and heating up on the comparable value because of the fact the chilly water. there is an episode of the prepare nutrients Detectives on the nutrients community that they did an test in this. Chem a hundred and one in college too.

Answer 6

I'm trying to dig back to my high school science days. What I do remember is that is a molecular thing. Something to do with the heat actually brings the molecules closer or it has slowed them down, which enhances the speed at which they become a solid. I remember it being opposite of what you would think. I hope this helps put you on track.

Answer 7

it is the rate that btu are transferred from the water to the surrounding air. there is a greater amount of btu's exchanged from hot water to cold air than cold water to cold air.

Here's a good link to describe it better than I can.

Answer 8

somthing with a faster molecule i really dunt remember
