To determine

The correct option for the statement “When air is saturated”.

Answer to Problem 10RAT

The correct option for the statement “When air is saturated” is option (c).

Explanation of Solution

The saturation of air is the point or the stage where no more amounts of water molecules dissolved in the air at the given temperature, pressure, and the amount of air. At the saturation stage, the condensation and evaporation rates freeze that is, the condensation rate becomes equal to the evaporation rate.

The relative humidity of the air at the same temperature and pressure is $100\%$ for its saturation condition. However, if any of the above factor changes then its saturation point and relative humidity changes.

Conclusion:

Therefore, the correct option for the statement “When air is saturated” is option (c).
