The boiling point of water (or other liquids) depends on the pressure acting on it. As you increase the altitude, the atmospheric pressure decreases and as it does, the boiling point of the liquid decreases. The atmospheric pressure at the summit of Mount Everest is approx one thrid the pressure at sea level and so water boils at approx 71 deg C.
At the boiling point a change of phase exist: from liquid to gas.
Boiling point elevation
These values depends (specially the boiling point) on the pressure.
At the boiling point the liquid phase is changed to a gas phase.
The boiling point is not changed.
yes the boiling point changes with elevation. the higher the elevation the lower the boiling point.
What is the phase change in evaporation
Boiling point.
Boiling point is an example of a phase change of matter (from liquid to gas).
Any added impurity can change the boiling point of a liquid.
I am not sure but may be it is because none of the substances have a fixed boiling point. The substance starts changing its state from liquid to gas before the mentioned boiling point . For example Boiling point of H2O is 100.but it change it changes its state before it.Therefore there are boiling range not boiling point.
A change in boiling point typically indicates a change in the intermolecular forces of a substance. For example, adding a solute to a solvent will usually increase the boiling point due to the formation of new intermolecular interactions. Conversely, a decrease in boiling point may signal a weaker intermolecular force, as seen in solutions or mixtures.
