Question

Define the term: Boiling point.

Answer 1

Boiling point:

• It is the temperature at which any liquid starts to boil.
• The boiling point of a liquid is the temperature at which the vapor pressure of the liquid becomes equal to the atmospheric pressure.
• At this temperature, the liquid is converted into a vapor.

For example, at sea level, the boiling point of water is ${100}^{\circ }C$ but at 2000 meters altitude the boiling point is ${98}^{\circ }C$.
