What is the boiling point of water

In summary, The typical atmospheric pressure in Breckenridge, Colorado is 520 torr. Using the ΔH value of 40.7 kJ/mol for water, the boiling point of water in Breckenridge can be calculated. To condense steam to liquid water at 331°C, a certain pressure must be applied, which can be determined by using Antoine's equation or the Clausius-Clapeyron equation.

It can be calculated from first principles. Look up the Clausius-Clapeyron equation on wikipedia (http://en.wikipedia.org/wiki/Clausius-Clapeyron_relation, the most useful from of the equation is under the applications section) or preferably in your chemistry text.
 

What is the boiling point of water?

The boiling point of water is the temperature at which water changes from a liquid to a gas. This occurs when the vapor pressure of the liquid is equal to the atmospheric pressure.

What is the boiling point of water in degrees Celsius?

The boiling point of water in degrees Celsius is 100 degrees. This is equivalent to 212 degrees Fahrenheit and 373.15 Kelvin.

Why does the boiling point of water change at higher altitudes?

The boiling point of water decreases at higher altitudes because the atmospheric pressure is lower. This means that the vapor pressure of the liquid only needs to reach a lower point to equal the atmospheric pressure and cause boiling.

Does the boiling point of water change with the amount of dissolved substances?

Yes, the boiling point of water can change with the amount of dissolved substances. This is because the dissolved substances can alter the vapor pressure of the liquid, making it harder or easier to reach the boiling point.

What is the significance of the boiling point of water?

The boiling point of water is an important physical property that is used in many everyday applications. It is also used in scientific experiments and can help determine the purity of a substance.
