Boiling temperature of water?
Verified Answer
Boiling temperature of water?
As a liquid is heated, its temperature increases. As its temperature increases, the molecules of the liquid gain energy and their kinetic energy increases. As the kinetic energy increases, the molecular motion increases and the molecules of the liquid overcome the force of attraction between them.
On continuous heating, a particular temperature is reached where the molecules of the liquid leave the surface in the form of vapour. This produces a pressure above the liquid equal to the atmospheric pressure and the liquid starts boiling.
At an atmospheric pressure of exactly 760mm Hg (1 atm), the temperature at which a liquid boils is called the normal boiling point of the liquid. For water, the vapour pressure reaches the standard atmospheric pressure of 1 atmosphere at 100 deg C. So the normal boiling point of water is 100 deg C (212 deg F or 373K).The boiling point of pure water increases on the addition of soluble substances such as sugar or common salt.

Boiling temperature of water?
The simple answer to this question is that the boiling point of water is 100 C or 212 F at 1 atmosphere of pressure (sea level). However, the value is not a constant. The boiling point of water depends on the atmospheric pressure, which changes according to elevation.
