Water vapor |
|
|
The phase transition by which a liquid is changed to a vapor (gas). |
Evaporation |
|
|
The phase transition by which a solid is changed into vapor (a gas) without passing through the liquid phase. |
Sublimation |
|
|
T/F: warm air can hold more water vapor than cold air. |
True |
|
|
The maximum possible quantity of water vapor that a parcel of air can hold at any given temperature and pressure is what? |
Saturation |
|
|
This means an air parcel contains all the water vapor it can hold. |
Saturated |
|
|
This means it has the capacity to hold more water. |
Unsaturated |
|
|
The ratio, usually expressed as a percentage, of water vapor actually in the air parcel compared to the amount of water vapor the air could hold at a particular temperature and pressure. |
Relative himidity |
