Water vapor enters the air as water at the surface evaporates or as plants transpire water vapor from their leaves.
Dew is the water that has condensed on a cool surface overnight from water vapor in the air.
When air holds the maximum amount of water vapor it can, we say it is saturated.
When you exhale, you release moisture from your lungs into the air as water vapor, which is why the exhaled air contains more water vapor than the inhaled air. This moisture comes from the air you breathe in, as your body extracts oxygen and releases carbon dioxide and water vapor during the process of respiration.
Water vapor is always present in the air because water molecules are constantly evaporating from oceans, rivers, lakes, and other bodies of water, as well as from plants and soil. This constant evaporation releases water vapor into the atmosphere, where it can remain suspended as humidity in the air.
Water vapor in the air can form clouds, fog, or mist depending on conditions such as temperature and humidity.

Water vapor in the air is water in the form of a gas.
This process is called evaporation. It occurs when water molecules gain enough energy to break free from the liquid phase and enter the surrounding air as water vapor.
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.
Evaporation
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.
The process is called evaporation. It occurs when molecules of liquid water gain enough energy to break free from the surface and enter the air as water vapor. This process is driven by heat energy from the surroundings.
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.
water vapor
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.
