No. Humid air is lighter than dry air. Although liquid water is much heavier than air, when it evaporates it becomes lighter than air. This is because any substance in gas form contains exactly the same number of particles in the same volume. That means that the weight of a gas is determined by the weight of the individual molecules in the gas.
Pure oxygen (two atoms of oxygen) has a relative weight of about 32 whereas pure nitrogen (two atoms of nitrogen) has a relative weight of 28. Pure carbon dioxide 12 +2x16 is 44, much heavier than either. The average relative weight of air being mostly nitrogen (78%) and oxygen (21%) is about 29. Compare that to the relative weight of pure water vapor--18.
When water vapor is mixed in with dry air, the relatively lighter water molecules displace some of the heaver nitrogen, oxygen, and carbon dioxide molecules making the humid air lighter. And the more humid the air is the more lightweight molecules in the mix and the lighter it is.

The difference between wet-bulb and dry-bulb temperature is called?
The difference between wet-bulb and dry-bulb temperature is called the Wet-Bulb Depression. It is a measure of air humidity, with a larger depression indicating higher humidity levels.
What does wet bulb depression depend on?
Wet bulb depression depends on the humidity level in the air. It is the difference between the dry bulb temperature and the wet bulb temperature, and it indicates the cooling potential of evaporative cooling systems. A higher wet bulb depression indicates that the air is drier and has a greater capacity to absorb moisture.
What is a wet-bulb depression?
The wet-bulb depression (WBD) is the difference in temperature between the ambient air temperature (Ta) and the wet-bulb temperature (Tw), ie: WBD = (Ta-Tw), and is associated with the maximum possible lowering of air temperature (hence, the word "depression") that's possible by evaporation of water vapor into the air up to the 100% relative humidity point.
On a cold winter day the air temperature is 2C and the wet-bulb temperature is -1C What is the relative humidity at this location?
51%.... open to the Relative Humidity chart in the reference tables. the wet bulb temperature is -1C and the dry bulb temp. is 2C, making a difference of 3C. On RH chart, go down to 3C column (difference between the Wet bulb and dry bulb) until it intersects the dry bulb 2C. At this intersection is 51%
Why is the wet monsoon wet and the dry monsoon dry?
From October to May, the winter monsoons blow dry air from the northeast.The summer monsoons come in the middle of June.It picks up moisture from the ocean.People rely on the summer monsoons for rain.winter is cold climate and summer is hot
