Answer 1

For humidity you can imagine a glass of water and some sugar you want to add.

You start with just the water at 0% sugar. Then you start adding sugar and dissolving it to raise the sugar percentage.

Eventually you will reach a point where no matter how much you stir the water, the extra sugar just won’t dissolve anymore. That means your water is 100% saturated with sugar.

Basically the same thing with air and humidity where air->water and water->sugar.
