the % relative humidity id given by:
(A)
Pi+p
P1
X 100
(B) x 100
(C)
px
X 100
(D) (p + Pı) x 100

Answer 1

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature.

RH=

P

s

P

×100

Answer 2

Explanation:

The partial pressure ofH2O(g) is P and equilibrium vapor pressure ofH2O(l)is Ps.

However, the percentage of relative humidity is the ratio of the partial pressure of water vapor to that of the equilibrium vapor pressure of water at that particular temperature into 100.

Hence,



RH=P/Ps×100

Thus option b is the correct option
