Is it true that hot water freezes faster than cold water or that cold water boils faster than hot water?

Because it takes cold water some time to reach the temperature of hot water, cold water clearly takes longer to boil than hot water does. “It all depends on how fast the cooling occurs, and it turns out that hot water will not freeze before cold water but will freeze before lukewarm water.

Does cold water or hot water freeze faster?

Yes — a general explanation. Hot water can in fact freeze faster than cold water for a wide range of experimental conditions. This phenomenon is extremely counterintuitive, and surprising even to most scientists, but it is in fact real. It has been seen and studied in numerous experiments.

Does cold water boil faster than room temperature?

Despite the common myth that cold water boils faster than hot, this is actually not true! Cold water does absorb heat faster than hot water, which may be the origin of this myth. However, once cold water reaches the temperature of hot water, its heating rate slows down and it takes just as long to boil.

Does cold water boil faster than hot water experiment?

The claim is repeated so often that many people accept it as fact. But according to scientists, the notion that a body of cold water will reach boiling temperature more quickly than an identical body of hot water under the same parameters is simply false.

Does hot water freeze faster than cold water independent variable?

It’s an age-old question with a simple answer: no. When the temperature of the water in each container reaches just about 0°C it will undergo the same changes as it moves from a liquid to a solid, and it will take the same amount of time to begin forming tiny ice crystals. …

Why does hot water freeze faster than cold Quora?

hot water have enough space to get stuck( means being ice) but cold one need some more time to have enough space to get stuck. because of this, hot one is freeze faster than cold one.

Why does hot water freeze more quickly?

The Mpemba effect is the observation that warm water freezes more quickly than cold water. Hence the faster freezing. Another is that warm water evaporates rapidly and since this is an endothermic process, it cools the water making it freeze more quickly.

Why does hot water freeze faster then cold water?

How long does it take for hot water to freeze in a freezer?

In a freezer, it will take from 1 hour to two hours if you what to get ice cubes at a temperature of 0° F. If your water is cold or really hot, the water will freeze even faster (around 45 minutes). This paradox we call the Mpemba effect.

At what temperature does boiling water freeze instantly?

This is known as the triple point, and temperatures need to reach 0.01°C (32.018°F) for it to happen, Uttal explains. When you boil water, you’re adding energy to water in its liquid state.

Does hot water freeze quicker?

Hot water freezes faster than cold, known as the Mpemba effect. The Mpemba effect occurs when two bodies of water with different temperatures are exposed to the same subzero surroundings and the hotter water freezes first.

Which will freeze first hot water or cold water?

Hot water freezes faster than cold, known as the Mpemba effect. Evaporation is the strongest candidate to explain the Mpemba effect. As hot water placed in an open container begins to cool, the overall mass decreases as some of the water evaporates. With less water to freeze, the process can take less time.

Why does hot water turn to ice faster than cold water?

The phenomenon of hot water turning into ice faster than cold water is known as the Mpemba effect, named after a Tanzanian student who observed his hot ice cream mix freezing more rapidly than the cold version.

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

There is no definitive explanation for why hot water may freeze faster than cold water. Different mechanisms come into play, depending on the conditions. The main factors appear to be: Evaporation – More hot water will evaporate than cold water, thus reducing the amount of water remaining to be frozen.

Does cold water put out fire faster than hot water?

Technically cold water will douse a fire faster than hot water, but of course it’s not that simple. Remember, water takes heat from the fire, it cools it. The main way it takes heat from the fire…
