Why do you have to heat water a long time in order for it to boil?

The boiling of water occurs when the vapor pressure of that water equals and exceed the atmospheric pressure. The reason it boils (tuns into a vapor/gas) is because the molecules of water get enough energy from the heat added that they can now escape the liquid phase and turn into gas.

∙ 14y agoThere are many reasons to boil water. The most common would be for cooking. Denser media transfer heat faster (and thus cook food faster). Baking is slow. Boiling is fast. Frying is faster still (because oil can be heated far hotter than water without boiling away).
Another variation on the cooking theme would be boiling water to sterilize it, or sterilize something boiled in it. Boiling water is guaranteed to kill most known harmful microbes.
Another reason would be to use the pressure from the resulting steam to generate electricity by turning a turbine. This is the way electricity is generated in nuclear power facilities.
Another would be for cooling -- water has a very high specific heat and when it absorbs enough heat to vaporize, it has also cooled the source of heat significantly.
Another reason would be distilling, removing the water, to leave behind substances that were dissolved within the water.
Another great reason to boil water is to occupy an agitated expectant father with time-consuming busywork when he is becoming a nuisance during his wife's labor.

How long doest take to boil water on a blue flame?
the lager pot will because it has more surface exposed to the heat.
How long will 1 gallon of water boil?
That's going to depend onthe temperature of the water when you start heating it, andhow fast you can transfer heat into it.
What is the time needed for water to boil and the effect of adding salt?
The time needed for water to boil depends on various factors such as the heat source and the amount of water. Generally, it takes around 5-10 minutes for water to boil. Adding salt to water increases its boiling point, meaning it takes longer for saltwater to reach boiling point compared to plain water. However, the difference in boiling time is minimal and may not be noticeable in everyday cooking.
How do you evaporate a bottle of water?
Easy, heat it up to a temperature above 100 degrees Celsius with a Bunsen or something
How long would it take a 55 gallon drum of liquid to boil?
That depends on 1 what the liquid was and 2 how much heat you are putting onto it.
How long does it take for the water to start boiling At what temperature does the water boil?
How long it takes water to boil depends on how much heat is being used. Water boils at 100 degrees C
How long does water have to boil to become sterile?
the water will not sterilize if you boil the water! the water still has bacteria in the water even if you heat it up; that's because some bacteria is heat resistant and will not die through the process.
How long do you boil polish sausage for?
45 minutes to an hour. bring water to a boil then simmer on low to medium heat.

How long do you boil a mouthgard?
you boil it in water
How long does it take for water to boil at Fahrenheit?
The time required to get water to boil depends upon the water initial temperature, the water mass, the nature of the heat source, the net heat transfer rate to the water, and the local barometric pressure.
How long doest take to boil water on a blue flame?
the lager pot will because it has more surface exposed to the heat.

How long does it take to boil non salted water?
The amount of time it takes to boil non-salted water depends on factors such as the volume of water and the heat source. Generally, it takes around 5-10 minutes for a standard pot of water to boil on a stovetop.
What is the benefit of specific heat?
One of the major benefits of specific heat is that it allows plants and animals not to freeze immediately since water takes a long time to freeze or boil.
Does food colouring affect the time it takes for water to boil?
Food colouring does not affect how long it takes for water to boil. Both clear water and water with food colouring boil at the same speed with no real obvious differences in time.
