Boiling Point – Definition and Pronunciation
What is Boiling Point?
Boiling point is the temperature at which a liquid’s vapor pressure equals the external pressure surrounding the liquid, causing it to turn into vapor. This phase transition occurs at a specific temperature for each substance, under given pressure conditions, and is a key characteristic in identifying and understanding substances.
Examples of Boiling Point
Boiling point takes place in a liquid when the vapour pressure is equal to the pressure in the liquid.
This pressure will allow the cargo at the bottom of a full shore tank to sustain a temperature perhaps one degree Centrigrade warmer than its atmospheric boiling point.
LNG is produced by cooling natural gas below its boiling point, -162 °C (-259 °F), and is stored in double-walled cryogenic containers at or slightly above atmospheric pressure.
