100 co at sea level, it varies what altitude your at.
Steam
Water vapour doesn't boil, but liquid water's boiling point is 100 degrees C, or 212 degrees F.boiling point is that point at which the vapour pressure of a liquid become equal to the atmospheric pressure at a particular temperature.for exampleboiling point of water is 100 degree Celsiusthat isat this temperature vapour pressure of water is equal to the atmospheric pressureso there is no boiling point of water vapour since it is not a liquid and boiling point is only determined for liquids not gases or vapours .also vapour has 540 kilo calories of heat known as latent heat of vapourisation at 100 degree celsius.
Ethylene glycol has a higher boiling point and a lower vapour pressure than water.
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
It does not exist except as part of water - it does not exist in isolation so can have no boiling point as boiling happens when vapour pressure equals the external pressure.
boiling point is a property which depends upon the atmospheric pressure. when vapour pressure of water is equal to external is called its boiling point.. if pressure is equal to atmospheric pressure ,boiling point is 100 degree celcius.
At 100 degree celsius water starts boiling. It starts changing into water vapour. 100 degree celsius is the boiling point of water.
Boiling point is the temperature at which the vapour pressure of liquid equals the pressure surrounding the liquid and the liquid changes into vapour whereas, normal boiling point can be defined as the case in which, vapour pressure of liquid equals defined atmospheric pressure at sea level, 1 atmosphere.
Boiling is the phenomenon in which saturated vapour pressure becomes equal to the external pressure. Hence as we increase the external pressure then the boiling point has to increase so as to attain that pressure
The boiling point of a liquid is defined as when the vapour pressure of that liquid is equal to the atmospheric pressure. On mountains, the air pressure is lower than at sea level, so it follows that the boiling point of water is lower there.
Boiling
Water vapour. An example is rain clouds in the sky.If the water is heated to boiling point in a kettle or furnace boiler, the very hot vapour is commonly called steam.
