Question:-
If the volume of moist air with 50% relative humidity is isothermally reduced to half its original volume, then relative humidity of moist air becomes
Option (A)
25%
Option (B)
60%
Option(C)
75%
Option(D)
100%
Correct Option:
(D)
Question Solution:
Æ1 = (mv1/ms) Æ2 = (mv2/ms)
(Æ2/Æ1) = (mv2/mv1) = {(P1V1 x R T2)/(RT1 x P2.V2)} = 2
Æ2 = 2 x 50% = 100%
T1 = T2; V2 = (V1/2)
