Homework Statement
The temperature of a room is 25 degree Celsius and its relative humidity (RH) is 60%.If the temperature is lowered to 15 degree Celsius,what fraction of water vapor gets condensed?
Saturated Vapour Pressure(SVP25)at 25 degree celsius = 23.7mmHg
S.V.P.15=12.8mmHg
Homework Equations
The Attempt at a Solution
RH= (m1/M)*100%
where m1= mass of water vapour present in the room ,at 25 deg celsius
M=mass of water vapour required to saturate the same volume of air
therefore 0.6M=m1
At 15 degrees Celsius,water vapour present in the room gets condensed,so the room is now saturated(m2) and RH is now 100% ?
If so fraction of water vapour condensed = (m1-m2)/m1?
But I don't know how I'm supposed to find m2.
Hope someone can help.
Thanks
