The relative humidity is the amount of water vapor the air is holding right now as a percentage of what it would be holding if it were saturated. If relative humidity is 20 percent, for example, the air contains 20 percent of the water vapor that it could potentially hold at that temperature. If you increase the temperature, however, the amount of water vapor the air can hold increases, so the relative humidity decreases.

The answer is true because relative humidity tells about an amount of water vapor present and not on the amount of liquid present.
So as the air gets wet it decreases water vapor but increases liquid quantity so the given answer is correct.

Relative humidity is about the quantity of water vapour dissolved in air. When air gets wet, part of vapour gets converted into liquid water. Thus the quantity of water vapour left in air decreases. So, the relative humidity decreases.

R.H increases as the air get wet.
In the psychometric chart if you draw a vertical upward line which indicates the humidification process (add of water vapour) and see there would be an increase in Relative humidity.

The relative humidity is the difference between dry-bulb temperature and wet bulb temperature.
- If dry bulb temp. Increase then RH will increase.
- If wet bulb temp. Increase then RH will decrease.
- If dry bulb temp. Increase then RH will increase.
- If wet bulb temp. Increase then RH will decrease.

Relative humidity decreases when the air gets wet. It can be noticed in winter season, during winter season the heat pump supplies hot and humidified air.

The relative humidity is the measure of moisture in air at any given temperature and pressure, so when the air gets wet, Rh should increase, not decrease.

Relative humidity is a measure of the amount of water droplets in the air, as air get wet means the amount of water particle increases. So RH increases.
