Question

Let $p$ and $p _{ s }$ the partial pressure or $H _{2} O ( g )$ and vapour pressure of $H _{2} O ( I )$ respectively. Then the % relative humidity is given by

(A) $\frac{p_{s}+p}{p_{s}} \times 100$

(B) $\frac{p}{p_{s}} \times 100$

(C) $\frac{p_{s}}{p} \times 100$

(D) $\left(p+p_{s}\right) \times 100$

Answer 1

The % relative humidity will be $\frac{p}{p_{s}} \times 100$. So, The correct option of this question is (B).
