What temperature does water boil ?

What temperature does water boil ?

The temperature at which water boils is 100 degree Celsius or 212 degree Fahrenheit. This temperature is relevant under the circumstances where the atmospheric pressure is one, which is the force exerted on a surface by the air above it.

To begin with lets understand the concept of boiling and the factors which affect the temperature at which it boils. Boiling of water is a state where the internal pressure equals the pressure of the atmosphere above the surface of water. The internal pressure of any liquid is the molecular activity which has the capacity to change it to gas. When we expose water to a certain amount of heat the molecules of water will start to move faster so as to match the external pressure of the air.

As soon as the pressures equate, the pressure of the air above the water is unable to keep the water still. As a result after certain heat exposure, the water bubbles and thus changes to vapor.

There are 2 major factors which affect at What temperature does water boil. These 2 factors are the atmospheric pressure and the purity content of water. As commonly observed the temperature at which the water boils changes to a large extent depending on the atmospheric pressure it is facing. The elevation of a place with regard to the sea level is the factor which plays a major role in determining the atmospheric pressure. As the elevation increases, the atmospheric pressure falls and vice-versa. At The places where the atmospheric pressure is low, water boils at a temperature lower than 100 degree Celsius. For example at Mount Everest, the water will boil at just 72 degree Celsius. Similarly when the atmospheric pressure is high water will need a lot more than 100 degrees Celsius to come to a boil. High atmospheric pressures are found below the sea level. The boiling point of water drops one degree Celsius or 1.8 degrees Fahrenheit with a mere increase of 300 meters in the altitude.

The other thing which affects the temperature at which the water boils is its purity. Water is a compound which contains molecules of hydrogen and oxygen. The molecular formula of water H2O is its purest form which is hardest to sustain. Even in a very controlled environment such as in a laboratory the purity of water is difficult to control. There are always some salts, chemicals or any other impurities which are bound to be present in water.

If the water has salt or any other form of impurity, it will take temperatures higher than 100 degrees Celsius to make it boil. Pure water will boil at exactly 99.98 degrees Celsius. The phenomenon which explains the effect of water’s purity on its boiling point is known as Boiling point elevation. As the impurities are increased the boiling point of water rises. For example the water of Dead Sea will boil at a temperature of 101.7 degrees Celsius.

So to Summarize What temperature does water boil ?

On a Layman’s term 100 degree Celsius or 212 degree Fahrenheit, but taking into Consideration other factors in can be from anywhere 72 degree Celsius to 101.7 Degree Celsius.

Find out at what temperature does water boil

If you are not sure on what temperate does water boil, you can search through internet or you can check books to know the rate at which it usually occurs. In different environment along with various altitudes, water boils. Therefore, you can’t provide exact temperature rate until you are not sure about your environmental change … Continue reading
