Chapter 18 Flashcards
Humidity
Amount of water vapor in the air
Precipitation
Any form of water that falls from a cloud
_____ is the most important gas in the atmosphere
Water vapor
The process of changing state requires that ______ is transferred in the form of _____
Energy; heat
Latent heat
Does not change temperature. Latent means hidden
Evaporation
Liquid to gas
Condensation
Water vapor into liquid
When saturated, ______ air contains more water vapor than saturated ______ air
Warm; cold
Relative humidity
Ratio of air’s water vapor to how much water vapor the air can hold
When water vapor in air constant, lower air temp = ___ relative humidity
Increase
Dew point
Temperature at which saturation occurs
Psychrometer measures:
Measures relative humidity and dew point
When air is compressed, it shows in crease in ______
Temperature
Dry adiabatic rate
Rate of cooling or heating that is applied to unsaturated air
Wet adiabatic rate
Rate of cooling caused by amount of latent heat (slower than dry adiabatic rate)
