Cold water...but if the water is heated than let still to room temp, it will freeze faster than regular room temp water *Because the time taken for something to cool to the temperature of its surroundings is proportional to the temperature (Newton's Law of Cooling and proceeding from there), the object with the higher temperature will take longer, thus the cold water freezes first. If the objects have the same initial temperature, they will take the same time to freeze (assuming identical conditions and a constant temperature in the surroundings for all objects). The above answer would be correct in realistic terms because boiling 'hard' water removes the dissolved ions from it (you may have noticed the "fur" in an electric jug) and raises the freezing temperature compared to unboiled water.

A hypothesis for which freezes the fastest cold or hot water?

A hypothesis for which freezes the fastest between cold and hot water could be that hot water freezes faster than cold water. This phenomenon, known as the Mpemba effect, has been observed under specific conditions where hot water cools faster than cold water due to factors such as evaporation and convection currents. This hypothesis would need to be tested through controlled experiments to draw a conclusion.


Witch freeze faster cold water or hot water?

I believe hot water freezes faster because it is supercooled. Cold water is non-supercooled. When cold water freezes ice crystals form and float to the top, forming a layer of ice over the top of the water, so the layer of ice stops evaporation . While the hot water, which is probably no longer hot in the freezer,when it does freeze, it freezes throughout, creating more or less of a slush before freezing solid.


Which freezes faster hot water or cold water?

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.


What does the sceintist Mpemba discovered?

The scientist Mpemba discovered the Mpemba effect, which is the phenomenon where hot water freezes faster than cold water under certain conditions. Despite being initially met with skepticism, the Mpemba effect has been observed and studied in various experiments.


What will freeze first cold hot or salt water and why?

hot

Does hot water freeze at a different ratev than cold water?

No hot water freezes, it has to cool off first.


Why is hot water freeze faster?

If you mean, compared with cold water, it doesn't. Hot water has to cool down first, before it freezes.


What would change for which freezes faster hot or cold water?

Hot Water


What expands when it is very hot or cold?

water, it freezes when it is cold and turns to steam when it is hot.


Which freezes first out of hot water and cold water?

Cold water. It doesn't have to cool as much as hot water does, thus it freezes faster. Under VERY specific labratory conditions, it can be made possible to have warmer water freeze faster, however, these conditions will not be present when you fill your ice tray. If you want ice, use cold water.


Which liquid will ferrze first hot water or cold water?

It would be cold water because if the freezing point for water is 0 degrees. and say the cold water is 10 degrees and the hot water 90 degrees, the cold water is closer to the freezing point than the hot water and so freezes quicker


Which freezes faster cold warm or hot water?

The process of water freezing into ice involves the temperature of water being lowered to 32 degrees Celsius. Hot water will take longer to freeze because the difference between the temperature of hot water and 32 degrees is greater than the temperature of cold water and 32 degrees.


What gets cold first hot or cold water?

Isn't cold water already cold? I would say cold water gets cold first. I've heard that hot water freezes faster than cold water.


Can hot or cold water freeze faster?

Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.

Does laundry dry better outside when it is cold?

no because the air freezes the water when its cold but if its sunny and hot it evaporates the water
