The temperature at which air becomes saturated and water vapor begins to condense is called the __________.

dew point

The measure of how much water vapor is in the air compared to the maximum amount of water vapor that can be held at that temperature is __________.

relative humidity

The amount of water vapor present in a given mass of air is known as __________.

specific humidity

Air that contains the maximum amount of water vapor possible at a given temperature is referred to as __________.

saturated air

An instrument used to measure relative humidity by comparing temperatures of wet and dry bulbs is called a __________.

psychrometer

Clouds form when air rises and cools, leading to condensation of water vapor. This process requires __________ temperature and adequate amounts of __________ in the air.

cooler; moisture

The formula for relative humidity is __________.

(actual vapor pressure / saturation vapor pressure) x 100%

Latent heat is defined as the amount of __________ required to change a substance from one state to another without changing its __________.

energy; temperature

The process by which liquid water turns into vapor is called __________, while the conversion of vapor back to liquid is known as __________.

evaporation; condensation

The direct transition from solid to gas without passing through the liquid phase is referred to as __________.

sublimation

As air rises, it cools due to __________, which is the cooling of air due to a decrease in pressure as it ascends.

adiabatic cooling

To visualize the changes of water from one state to another, a __________ graph is utilized to show the relationship between temperature and phase changes.

phase change

In the process of precipitation, water droplets combine and grow heavy enough to fall back to the ground as __________, including rain, snow, sleet, or hail, depending on atmospheric conditions.

precipitation

A dew point chart provides information on the __________ at which dew forms, indicating the humidity level of the air.

temperature

A relative humidity table shows the __________ of the air at various temperatures, providing insight into moisture content.

percentage of moisture
