boiling - definition - thermodynamics and statistical mechanics

Definition: The very rapid conversion of a liquid into vapor by the violent and rapid creation of bubbles. It occurs when the temperature reaches such a value that the saturated vapor pressure of the liquid equals the pressure of the atmosphere above the fluid. Bubbles form in the liquid and rise to the surface, creating the familiar turbulent fluid. The temperature of the liquid cannot be raised above the boiling point until it has been entirely converted to gas.

Examples: When water is heated to 100oC, it boils and the liquid water rapidly turns into steam.
