The normal boiling point
(also called the atmospheric boiling point or the atmospheric pressure boiling point)
is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure at sea level, 1 atmosphere.
The normal boiling point of water is about 100 degrees Celsius at a pressure of 1 ATM (i.e., 101.325 kPa).
General Useful Information:
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure, but the environmental pressure may or may not be equal to the atmospheric pressure at sea level, 1 ATM.
If the surrounding environmental pressure is less than atmospheric pressure, then the boiling point is less than the normal boiling point.
If the surrounding environmental pressure is greater than atmospheric pressure, then the boiling point is greater than the normal boiling point.
At the boiling point, adding enough heat to the liquid will cause the liquid to vaporize (that is boil or form a gas).

What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
Why do the boiling point of water decrease on climbing up the higher altitude?
Water usually boils at 212F or 100C at sea level. As you go higher up in the atmosphere (higher altitude), the amount of atmosphere pushing down on you decreases, hence the pressure decreases. Water boils when the vapor pressure of the water equals the atmospheric pressure. Vapor pressure increases with increasing temperature, so when there is less atmospheric pressure, a smaller vapor pressure is required to get the water boiling, hence a lower boiling temperature.
When the vapor pressure of a liquid is equal to the atmospheric pressure the liquid .?
it begins to boil - Monsy
What is the relationship between presssure and the boiling point of Liquids?
Boiling point is nothing but point at which liquid starts changing from liquid state to vapor state. liquid changes to vapor when vapor pressure equal to surrounding pressure. so if surrounding pressure is less boiling point is less and boiling point is high if surrounding pressure is high this point is on view of pressure
How can the boiling point of a liquid be raised without adding soluble impurity?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, or the pressure above the liquid. So, to increase the boiling point without adding a solute, one can increase the pressure above the liquid.
What is the relationship of boiling point with atmospheric pressure?
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
What is the boiling point of liquids?
212 Degrees Fahrenheit,100 Degrees Celsius
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
What is the temperature where the vapor pressure of a liquid equals atmospheric pressure?
The boiling point of the liquid.
The conversation of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
When is boiling point?
Boiling point is when the liquids pressure equals the pressure of the atmosphere.
When vapor pressure equals atomospheric pressure what is the liquid?
The Liquid will turn into gas. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. If the liquid is open to the atmosphere (that is, not in a sealed vessel), it is not possible to sustain a pressure greater than the atmospheric pressure, because the vapor will simply expand until its pressure equals that of the atmosphere.
When vapor pressure equals atmospheric pressure at the surface of a liquid it has reached its what?
boling takes place
What is the relationship between pressure and the boiling points of liquid?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
Why does water boil at a lower temperature on a mountain than sea level?
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
