The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
Water boils at 100 degrees Celsius at standard atmospheric pressure because that is the temperature at which its vapor pressure equals the atmospheric pressure. If the temperature is increased beyond 100 degrees Celsius, the vapor pressure exceeds the atmospheric pressure, causing the water to evaporate rapidly but not necessarily boil.
An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will boil.
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).
To determine the normal boiling point using vapor pressure and temperature, one can plot a graph of vapor pressure versus temperature and identify the temperature at which the vapor pressure equals the standard atmospheric pressure of 1 atm. This temperature corresponds to the normal boiling point of the substance.
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.
The boiling point of the liquid.
This temperature is called the boiling point, and indicates the temperature at which a liquid will assume a gaseous state, given the addition of the heat of vaporization.That is the boiling point.
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 the vapor pressure equals atmospheric pressure at the surface of a liquid, it has reached its boiling point. This is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on it by the surrounding atmosphere, causing the liquid to change into vapor.
Water boils at 100 degrees Celsius at standard atmospheric pressure because that is the temperature at which its vapor pressure equals the atmospheric pressure. If the temperature is increased beyond 100 degrees Celsius, the vapor pressure exceeds the atmospheric pressure, causing the water to evaporate rapidly but not necessarily boil.
The temperature at which the pressure of the evaporating liquid equals the atmospheric pressure of the surroundings. For pure water at sea level on earth, this is 100 degrees celsius.
An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will boil.

The temperature at which a liquid and gas are in equilibrium is called the boiling point. At this temperature, the vapor pressure of the liquid equals the atmospheric pressure, allowing the liquid to change into gas and vice versa at a constant rate.
Its vapor pressure equals atmospheric pressure.
To determine the normal boiling point using vapor pressure and temperature, one can plot a graph of vapor pressure versus temperature and identify the temperature at which the vapor pressure equals the standard atmospheric pressure of 1 atm.
