Flashcards in CH4 - Atmospheric Density Deck (6)
Which is more dense cold or hot air?
Cold air because it's compact, whilst hot air is expanded so molecules have more space in between.
What happen with density if humidity is increased?
Density will decrease.
Characteristics of cold and hot air.
Cold air = less water vapour = < density
Hot air = more water vapour = > density
Density can be splitted into two different types, which are... ?
Relative density and density altitude.
What are the factors affecting air density?
Temperature, humidity and pressure.
