No. For a lot of reasons, really. But usually, the more matter that exists, the more you need to put into/take from it to incite a change.
If you have a drop of water, you only need get rid of a little energy to freeze it.
If you have a lot, you've got a lot of energy to get rid of.
Let's say we have a deep pond on a cold winter day. The surface will freeze first, why?
1. It's nearer the cold air. The energy from the surface is lost to the air, whereas deeper down you only lose it to other water molecules..so it just stays in the water.
2. Deep down, the water is under a lot of pressure. It's got the weight of the rest of the water on top of it. This crushes the water and makes it slightly more dense.
But ice is less dense than water! So to freeze the water deep down, you have to expand it even though it's being crushed. That's not easy to do. Whereas at the surface, it can - for the most part - just expand into the atmosphere. Which is easy to do.
Further to the above.
No it won't. Shallow water freezes faster. If you live in an area that sometimes gets below freezing (like where I live at the moment - brrr) you'll know that puddles freeze really quickly, but garden ponds still have water beneath the icy surface. This is because water is unique in the fact that it gets less dense as a solid than it is as a liquid. So the solid ice floats leaving liquid below it. Which is good news for fish! This floating barrier also acts as insulation, preventing deeper water from freezing unless the temperature gets really cold.
Hot water can in fact freeze faster than cold water for a wide range of experimental conditions. This phenomenon is extremely counter- intuitive, and surprising even to most scientists, but it is in fact real.

The phenomenon that hot water may freeze faster than cold is often called the Mpemba effect. Because, no doubt, most readers are extremely skeptical at this point, we should begin by stating precisely what we mean by the Mpemba effect. We start with two containers of water, which are identical in shape, and which hold identical amounts of water. The only difference between the two is that the water in one is at a higher (uniform) temperature than the water in the other. Now we cool both containers, using the exact same cooling process for each container. Under some conditions the initially warmer water will freeze first. If this occurs, we have seen the Mpemba effect. Of course, the initially warmer water will not freeze before the initially cooler water for all initial conditions. If the hot water starts at 99.9°C, and the cold water at 0.01°C, then clearly under those circumstances, the initially cooler water will freeze first. However, under some conditions the initially warmer water will freeze first -- if that happens, you have seen the Mpemba effect. But you will not see the Mpemba effect for just any initial temperatures, container shapes, or cooling conditions.
d3tThis is a complete guess but I think that it's maybe because the cold gets trapped in the container?
The colder the environment, the quicker heat is transfered from the water to the environment, so yes.
The freezing point is the same.

No It's warm water the ? was what cools faster cool water is already cool so warm water will cool faster. Plus cool water gets warm Also back in the sixties a experiment was done Hot water froze faster than cold water by a minute . ( I remember this from the Weekly Reader report. lol lol ) I also believe it's meant to suggest when the water is at room temptureroom temperature.
Sounds as if you were trying to repeat the MpembaEffect. Apparently it was even known to Aristotle that to get a liquid to freeze faster, "warm it in the sun first".Enter Mpemba (circa 1950s?) who had known that warm liquids freeze faster than cool ones when placed in the frig.Much experiments and $$ later, the explanation is yet to arrive (maybe a Nobel?), but the optimum temps for the experiment are 35oC for the hot liquid and 5oC for the cold one.
At nightime, the plains cool faster than bodies of water. Therefore, it is warmer at seaside. At daytime, the plains warm faster than the sea. Therefore, it is cool to stay on the beach.
Cold water will freeze faster. Because the freezing point of water is 0oC, water that is closer to that point will freeze faster then hot water. This is because it will require less time to lower the temperature to the freezing point.
thermocline
Yes, usually.
rar i am not going to anser this
Mpemba effect ,water evaporates faster so it has less water so it freezes faster
The starting temperature will certainly affect the time it takes for water to freeze. By definition, the temperature will be the same for both the water that started warm as it is for the water that started cool when they both freeze. The time difference comes from going from warm (~85 degrees) to freezing (32 degrees) and from cool (~50 degrees) to freezing (32 degrees).
Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.

yes because you have to know which one grows faster with warm of cooler water..!
it would be in warm
Absolutely. Water must achieve a temperature below 32°F before it can freeze. The closer the water is to room temperature, the quicker it will freeze. There is a phenomenon in which warm water freezes and cold water not: In some regions(e.g. Siberia) it is possoble to pour boiling hot water to the ground and it will freeze even before it hits the bottom. This is possible as hot water's molecules are moving more heavily than those of cold water. Therefore the surface of the water is bigger and warmth can leave the molecules faster. I remember a report of a experiment at one of the university's found hot water froze faster by a inute.

AnswerHot water doesn't freeze fasterAccording to www.sciensational.com, hot water freezes faster than cold water.But I do not have any idea about your question.lllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll
In the beginning of what ? At the end of what ?Do you mean "Why does hot water cool faster than cool water ?" ?Because the rate at which heat passes from a warm object to a cool objectdepends on the difference in their temperatures. So, as the warm objectbecomes less warm and the difference in their temperatures becomes smaller,the rate at which heat flows between them also becomes less.
