Humidity is the amount of water vapor in the air, with warm air able to absorb much more water vapor than cold air. Relative humidity compares the actual amount of water vapor in the air to the total amount the air can hold at a given temperature, with 100% relative humidity occurring when the air can hold no more water vapor.

1. What is
humidity ?

2. Humidity
It is the amount of water vapor in the air .
The higher the temperature the more water
vapor it can hold
Warm air can absorb much more water vapor
than cold air

3. Relative Humidity
The amount of water vapor in the air compared
to the total amount that air can hold at that
temperature .
When water can’t hold water vapor anymore the
relative humidity is 100%
