Boiling point :
The temperature at which the liquid boils and turns to vapour is called the boiling point.
In other word, the boiling point of a substance is the temperature at which the vapour pressure of the liquid equals the pressure surrounding the liquid.
When a liquid is heated, it eventually reaches a temperature at which the vapour pressure is large enough that bubbles form inside the body of the liquid. This temperature is called the boiling point.
The boiling point of a liquid varies depending upon the surrounding environmental pressure.
For any liquid boiling point is high in high pressure than its atmospheric pressure.
For a given pressure, different liquids boil at different temperatures.
For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 2,000 meters (6,600 ft) altitude.
