Humidity- The amount of water vapor present in the air.

Air does not always contain the same amount of water
vapor.

At warmer temperatures, the molecules of water vapor in air move quickly and don’t
easily come together.

At cooler temperatures, molecules in air move more
slowly.

The slower movement allows water vapor molecules to stick together and form droplets of liquid water.

Condensation- the formation of liquid water from water
vapor.

RelativeHumidity

Relative Humidity- is a measure of the amount of
water vapor present in the air compared to the amount needed for saturation at a
specific temperature.

The amount of water vapor in the air at any given time is
usually less than that required to saturate the air.

The most common units for vapor density are gm/m3.
