Dew Point

Dew point explained in an easy to understand way:

Imagine you have a cup of water and you're slowly adding sugar, stirring each time. At first, the sugar dissolves easily, but eventually, you reach a point where no more sugar will dissolve and it starts to settle at the bottom. This is similar to how the air can hold moisture: the air can hold water vapor until it reaches a specific temperature, called the dew point, where it can no longer hold all the moisture, causing condensation to occur. Just like the sugar reaches a saturation point in the water, the air reaches a saturation point at the dew point, where excess moisture turns into droplets, just as excess sugar settles out of the solution.
