Boiling Point Meaning
What is Boiling Point:
The boiling point is known in physics and chemistry as the temperature at which the vapor pressure of a substance equals the external atmospheric pressure.
It is at boiling point when the passage of a substance in liquid state to the gaseous state in a tumultuous way. In fact, once the boiling point is reached, the temperature cannot rise any further.
The boiling point occurs under certain conditions of temperature and pressure. Furthermore, it varies from substance to substance, depending on its specific properties.
For example, the boiling point of water at sea level is 100 ° C, but when we begin to rise in the atmosphere, finding ourselves less atmospheric pressure, the temperature to reach the boiling point decreases.

Boiling point and melting point
The boiling point and the melting point are not the same, although they have in common being the moment when a substance passes from one state to another.
In the case of the melting point, this supposes the temperature at which a substance passes from the solid state to the liquid, while the boiling point refers to the temperature at which a liquid substance passes into the gaseous state.In this sense, the boiling point temperature will always be higher than the melting point.
