Hot water does not freeze faster than cold water. Nor does cold water boil faster than hot water. For water to freeze, you must remove enough heat to bring its temperature down to 0 C. The colder the water is, the less heat you have to remove before it freezes. I have no idea why this rumor is cirulating the net and the world. It is just totaly insane to even think that that could be true. If you have just heated the water to 100 degrese, then it has that much more to cool down to 0. If the waterisat 30 then it is obvious that the 30 degree would cool faster. Really now. It's not exactly a rumor, it's true...at least sometimes. In scientific communities it's called "The Mpemba Effect" and was named after a Tanzanian student named Erasto Mpemba who first raised the question in the late 60s. When a container of water is placed in a freezer, there are many factors which can affect the length of time it will take to freeze, and under the proper combination of circumstances, a given volume of hot water in a container may freeze faster than the same volume of cold water. So, the best answer is, "Sometimes."

Why does boiling water freeze faster than cold water?
The Mpemba effect, where hot water freezes faster than cold water, is a complex phenomenon that is not fully understood. Some possible explanations include faster evaporation of hot water, differences in dissolved gases, and changes in the structure of water molecules.
Does hot cold or salt water freeze faster?
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
Which hot or cold water will freeze faster?
In some cases, hot water can freeze faster than cold water due to the Mpemba effect. This phenomenon occurs because hot water can evaporate more quickly, which reduces the volume of the water and leads to faster cooling. However, there are many variables at play, so it is not a reliable method for freezing water quickly.
Which freezes first hot cold or salt water?
Salt water freezes before plain water because the presence of salt lowers the freezing point of the water. Cold water will freeze faster than hot water because the molecules in the cold water have less kinetic energy and are more likely to form solid ice structures.
How long do it take for hot water to freeze?
The time it takes for hot water to freeze depends on factors such as the initial temperature of the hot water and the surrounding temperature. In general, hot water will freeze faster than cold water due to the Mpemba effect, which is the phenomenon where hot water freezes faster than cold water under certain conditions.
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.
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.
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.
Does soap freezes faster than water?
== ==
What freezes faster warm water or cold water?
Cold water, less energy must be removed from cold water to make it freeze. warm water has more energy which needs to be removed before it freezes. it is an urban myth that warm water freezes faster.
Why does boiling water freeze faster than cold water?
The Mpemba effect, where hot water freezes faster than cold water, is a complex phenomenon that is not fully understood. Some possible explanations include faster evaporation of hot water, differences in dissolved gases, and changes in the structure of water molecules.
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.
What freezes faster sugar water or fresh water?
Sugar water freezes faster than fresh water due to the presence of sugar molecules which disrupt the formation of ice crystals. This phenomenon is known as the Mpemba effect, where the solution with a higher concentration of solute freezes faster than the solution with a lower concentration of solute.
Does hot water freeeze at a diffferent rate than cold water?
yes, it freezes faster because it loses its temperature more quickly; while cold water maintains its temperature better
How does salt water freeze faster than tap water?
It doesn't. Tap water freezes faster than salt water.
Will tap water freeze faster than salt water?
Fresh water freezes faster than salt water, yes.
Does hot cold or salt water freeze faster?
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
