Answer:
The statement is false.
Explanation:
A unsaturated mass of air can become saturated in 3 ways:
1) Adding moisture to the initially unsaturated air till it becomes saturated.
2) Mixing of 2 different air masses initially unsaturated but the mixture becomes saturated.
3) Reducing the temperature of the surrounding so that the capacity to hold moisture of the air mass decreases until it becomes saturated.
