The maximum amount of water vapor air can hold at a given temperature

capacity

temperature at which water vapor condenses

dew point

When air is completely filled with water vapor

saturated

as temperature goes up the capacity goes ______

down

when the dry and wet bulb temperatures are very different the air is ____

dry

Which phase changes have latent heat gained

Melting & Vaporization

Where is ice melting ?

B-C

Does temperature change significantly during a phase change

No

Does the surrounding air warm or cool as clouds form

warms

Explain why sweating cools you down

As the sweat evaporates the sweat gains heat from your body

Phase change when water vapor becomes water

condensation

Which phase has the most energy

Gas

Can you see water vapor

no

What are the 2 examples of vaporization

Evaporation & boiling

What is the difference between evaporation and boiling

Boiling occurs throughout and evaporation only occurs at the surface

What is the formula of relative humidity

Humidity divided by capacity times 100

Can warm or cold air hold more water vapor

Warm

As the air warms up does the humidity have to change

No (humidity is not affected by temperature)

What time of day has the highest relative humidity

dawn

If the temperature decrease and the humidity remains constant does the relative humidity go up or down

up

Solid which is needed for condensation

Condensation nuclei

Do clouds form or evaporate as warm air rises

form

What are we looking at when we see our breathe ?

water

Was the air saturated when the sweat formed on the can?

yes

Explain why the orange does not get ruined ?

As the water freezes it releases latent heat into the orange

Can the relative humidity ever be 100% Relative humidity NO
