Term
|
Definition
| Process by which water molecules in liquid water escapes into the air as water vapor. |
|
|
Term
In this process water molecules gain energy. Those near the surface have more room and are able to move faster.
These molecules break away from the surface and go in between the air molecules. |

Term
|
Definition
| Water vapor molecules lose energy, slow down and stick together. |
|
|
Term
|
Definition
| The air is so full of water vapor it cannot hold another molecule. |
|
|
Term
| If a molecule evaporates then a molecule has to condense to make room for the evaporating molecule. |
|
Definition
|
|
Term
| the percentage of how much water vapor is in the air compared to how much water vapor the air can hold at a particular temperature. |

Definition
| the actual amount of water vapor in the air |
|
|
Term
| An instrument used to measure relative humidity. |
|
Definition
|
|
Term
| It has a wet thermometer bulb and a dry bulb. We compare the two to find the relative humidity. |
|
Definition
|
|
Term

Term
| 3 things needed to make a cloud |
|
Definition
1) water vapor
2) air cooled slightly below dew point.
3) a surface for the water droplets to cling to (condensation nuclei) |
|
