💧Humidity & Moisture

H20

What molecule sustains all life on earth?

weakly polarized, surface tension

The H20 molecule is [termly term]. It is attracted to other molecules, creating [term term].

When water freezes, it produces [term] geometries.

requires, colder

Evaporation [requires/releases] heat, making the surrounding environment [warmer/colder].

requires, colder

Sublimation [requires/releases] heat, making the surrounding environment [warmer/colder].

requires, colder

Melting [requires/releases] heat, making the surrounding environment [warmer/colder],

releases, warmer

deposition [requires/releases] heat, making the surrounding environment [warmer/cooler].

releases, warmer

condensation [requires/releases] heat, making the surrounding environment [warmer/cooler].

releases, warmer

freezing [requires/releases] heat, making the surrounding environment [warmer/cooler].

0, moving

Molecules with a temperature over [#] degrees Kelvin are constantly [term].

g/m^-3

units of absolute humidity

inversely proportional

temperature and relative humidity have a(n) [termly term] relationship

wet-bulb temperature

the lowest temperature that can be reached by evaporating water into the air. One of the main measures on a sling psychrometer.

between

The wet bulb temperature is always (term) the dew point temperature and the air temperature/dry bulb temperature.

less, decreasing, increasing

Colder air can hold [term] moisture, [term] the threshold for saturation and [terming] relative humidity even when moisture remains constant.

more, increasing, decreasing

Warmer air can hold [term] moisture, [term] the threshold for saturation and [terming] relative humidity even when moisture remains constant.

dew point temperature

The most reliable measure of humidity favored by many meteorologists, this is the temperature needed to reach saturation for a given amount of humidity.

dew point depression

T - Td, or the difference between temperature and dew point temperature

mass, water vapor, volume, variable, volume

absolute humidity — the ratio of the [term] of [term term] to the air [term] may be a(n) [term] measure of the air’s moisture content because air [term] increases and decreases as air rises and falls.

conserved variable

a variable that remains constant despite changing external factors is called what?

mixing ratio

the ratio of the mass of atmospheric water vapor to the mass of atmospheric dry air

specific humidity

the ratio of atmospheric water vapor to the mass of atmospheric dry air

relative humidity

the ratio of the actual mass of water vapor present in the atmosphere to the amount that would be present at saturation

vapor pressure

partial pressure due to the water vapor present in the atmosphere

saturated vapor pressure

partial pressure due to the water vapor that would be present in the atmosphere at saturation

saturation

occurs when the amount of water vapor in a parcel is at its maximum (when the parcel can no longer hold water)

parcel

a body of air with uniform dynamic and thermodynamic properties is called a…

cools, farther

when an air parcel rises, it (terms) because it is (termer) from the warm surface

warms, closer

when an air parcel sinks, it (terms) because it is (termer) from the warm surface

net condensation

overall condensation > overall evaporation

(or when there is more condensation than evaporation within a fluid or air parcel)

net evaporation

overall evaporation > overall condensation

(or when there is more evaporation than condensation within a fluid or air parcel)

saturation, equilibrium

(term) occurs when evaporation and condensation within an air parcel are equal, or at (term).
