um... the partial pressure at the boiling point always must be equal to the vapor pressure. This is true for all substances.
Added:
The partial pressure of a pure (100%) gaseous substance boiling from its pure liquid is 100% of total pressure, because its fully pure, so what else could be there.

What is the boiling point of bromine when the external pressure is 75 kPa?
The boiling point of bromine under a pressure of 75 kPa is approximately 58°C. At this pressure, the boiling point of bromine is lower than its usual boiling point of 58.8°C at standard atmospheric pressure.
How does the boiling point of a liquid vary with pressure?
Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.
How does abnormally low pressure affect the boiling point of a compound?
Abnormally low pressure decreases the boiling point of a compound because it reduces the pressure exerted on the liquid, making it easier for molecules to escape into the gas phase. This results in a lower energy requirement for the liquid to vaporize, lowering the boiling point.
What is the boiling point of NH3?
The boiling point of NH3 is -33,34 0C.
What is the boiling point of nitrogen and oxygen?
Nitrogen melts at 63.15 K or -210.00 °C or -346.00 °F. Nitrogen boils at 77.36 K or -195.79 °C or -320.3342 °F. Everything more you need can be found by using the link below. It will take you to the Wikipedia post on nitrogen, and knowledge is provided there for free.
What is the boiling point of oxygen in Celsius at 1atm of pressure?
The boiling point of oxygen at atmospheric pressure (1 atm) is -183 degrees Celsius.
How does the boiling point affect sugar water?
salt or sugar would lower the melting point and raise the boiling point. The salt or sugar would reduce the partial pressure of water in the solution (essentially more competition), effectively raising the boiling point.
Does chlorine or oxygen has higher boiling point?
Chlorine has a higher boiling point than oxygen. Chlorine's boiling point is -34.6 degrees Celsius, while oxygen's boiling point is -183 degrees Celsius.
When is boiling point?
Boiling point is when the liquids pressure equals the pressure of the atmosphere.
Why is boiling dependent on pressure?
Boiling is dependent on pressure because the pressure affects the boiling point of a substance. When the pressure is higher, the boiling point of a substance is also higher, and when the pressure is lower, the boiling point is lower. This is because pressure affects the vapor pressure of the substance, which needs to equal the atmospheric pressure for boiling to occur.
What is the boiling point of oxygen in c?
The boiling point of oxygen is -183 degrees Celsius.
Which has the lowest boiling point alcohol oxygen petrol?
Oxygen has the lowest boiling point of these. It is far below the boiling points of the others.
Why the boiling point of a pure liquid is usually reported along with the pressure at which the boiling point was measured?
The boiling point of a liquid depends on the pressure applied to it: higher pressure raises the boiling point and lower pressure decreases it. By reporting the boiling point along with the pressure, it allows for accurate comparison and reproducibility of experimental results, as different pressure conditions can affect the boiling point.
How does pressure affect boiling point of Methane?
At low pressure the boiling point is lowered and inverse.
Does the boiling point increase with pressure?
Yes, the boiling point of a substance increases with an increase in pressure.
Evaporation occurs at boilig point or before boiling point?
Water - or other liquids - will evaporate at practically any temperature. Boiling is defined as the temperature at which the partial vapor pressure is equal to the atmospheric pressure. In practical terms, it means that the boiling water (or other liquid) can't get any hotter assuming the pressure doesn't change. You'll also see lots of bubbles rising from the boiling liquid (but before it is boiling, there will also be a few bubbles).
How does pressure affect boiling point?
An increase in pressure raises the boiling point of a liquid because it takes more energy for the liquid molecules to escape the higher atmospheric pressure above them. Conversely, decreasing the pressure lowers the boiling point as it requires less energy for the molecules to overcome the reduced atmospheric pressure.
