# Question: How long does boiling water take to freeze?

Contents

How long does it take for boiling water to freeze? Anyway, normally, the approximate time is between three and four hours.

## Does boiling water actually freeze faster?

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. … The phenomenon that hot water may freeze faster than cold is often called the Mpemba effect.

## How long does it take for a cup of hot water to freeze?

Short answer: about 3 hours. Long answer: it not that simple. Liquids when freezing must first get to their freezing point. Then an amount of energy must be removed without changing temperature – the “latent heat” or heat of fusion.

## How long does it take water to freeze in freezer?

How Long Does it Take Water to Freeze in the Most Common Ice Trays? In the majority of circumstances where a regular upright home freezer is used, it will require approximately 3 to 4 hours for the water to freeze into usable cubes. This is only an average time for standard ice cube trays with 12 square spaces.

## Do hot water pipes freeze faster than cold?

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.

## Does hot water freeze faster Mythbusters?

If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases.

## What happens when you freeze boiled water?

The leading explanation for this strange phenomenon is fairly straightforward. Hot water evaporates more than cold water. As boiling water cools down, a small amount of its mass is turning to steam and floating away. Hot water freezes faster than colder water simply because less of it has to turn into ice.

## Can you put boiled water in the freezer?

In the freezer.

Just don’t stick it in the freezer when it’s boiling – or you’ll have the same temperature-related issues in your freezer as you would have in the fridge. Even so, you can freeze water and keep it a long time. Be sure to cover it – and to use a freezer-safe container.

## At what temperature does the water boil?

A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.
