If the rate of evaporation is y, and the rate of condensation is x, then, a vapour is saturated when
A
x > y
B
x
C
x = y
D
x \(\leq\) y
Verified Correct Answer: C.
Physical Principles & Numerical Solution
In a saturated vapour, the rate of evaporation (y) equals the rate of condensation (x). This means that the amount of vapor entering the gaseous phase is equal to the amount of vapour returning to the liquid phase, resulting in a stable concentration of vapour in the air.
