1. Water in gas form is called water vapour.
2. Dry air has a little water vapour.
3. Moist air has a lot water vapour.
4. Cold air can hold less water vapour than warm air.
5. The higher the temperature, the more water vapour air can hold.
6. Air that holds all the water vapour it can is called saturated air.
7. Saturated air feels very damp.
8. The amount of water vapour in the air compared to the amount it can hold is called relative humidity.
9. The highest relative humidity is 100%.
10. The lowest relative humidity is 0%.
On the back, give thoughtful responses to the following questions.
1. What happens if the air is saturated and the temperature drops?
Cold air cannot hold as much water.
The water vapour in the air will condense to clouds, fog, mist, or rain.
2. Explain why warmer temperatures can hold more water.
The particles in warmer air move faster and have more space between them.
There is more room for water vapour to fill.
