What would happen to the boiling point of a substance if the elevation were to rise?
The boiling point of the substance would reduce.......
By definition, the boiling point of a liquid is the temperature at which the vapour pressure of the liquid is equal to the ambient pressure, and bubbles of vapour form directly in the liquid. The
I do acknowledge that this definition is wordy, and it is the level of knowledge expected of a 1st year undergraduate chemist........ But this principle underlies vacuum distillation, where we can boil an otherwise involatile liquid by reducing the ambient pressure (by applying a vacuum) and reducing the temperature at which the vapour pressure of the liquid is equal to the ambient pressure.
The highest altitude city to which I have been was Denver, Colorado, approx. 1500 m above sea level. The boiling point of water is approx.
