Water vapor in the air is water in the form of a gas.
a cloud
Humidity means the amount of water vapor in the air. It begins with the letter H.

Water vapor is the invisible gaseous form of water. It is part of the air and moves freely in the air.In the higher altitudes as it cools, it may condense out of the air and become liquid water. If the droplets are small they will hang in a fog and form a cloud. If they clump together into bigger drops, they will fall as rain.
Water vapor in the air is water in the form of a gas.
Water vapor enters the air as water at the surface evaporates or as plants transpire water vapor from their leaves.
When water vapor is added to the air, the density of the air decreases. This is because water vapor molecules are less dense than dry air molecules.
The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.
Water vapor is water is gas form. Humdity is the amount of water the air can hold. So, they're both water in the air.

Relative humidity is a measure of the amount of water vapor in the air. It represents the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a specific temperature, expressed as a percentage.
It takes a lot of energy to turn water into water vapor. The amount of energy that the water gains to turn into water vapor begins to be transferred into the surrounding air. If the air is willing to take on more energy the water vapor condenses quicker. This is why hot air will hold more water vapor than cold air.
Saturated air is more dense.
Its ratio of the air's water vapor content to its water vapor capacity :)
Water vapor in air condenses into liquid water at the dew point temperature.
It may condense into clouds, or into precipitation, because cooler air cannot hold as much water vapor as warmer air.
