Question

Difference between vapour pressure and saturated vapour pressure

Answer 1

Answer:

Vapor pressure is a measurement of the amount of moisture in the air. It is technically the pressure of water vapor above a surface of water. When air reaches the saturation vapor pressure, the water vapor in it will condense. At this time, the dew point temperature is the same as the air temperature .

Answer 2

There is NO difference between vapour pressure and saturation pressure.

• Vapour pressure is the pressure exerted by the vapour on its condensed phase at a give temperature in a closed system.

• Saturation pressure is the pressure at which a liquid satrts to boil at a given temperature in a closed system.
