Name 7 air properties
Air takes up space
Air is composed of many gases
Air has weight/mass
Hot air expands/rises, cold air contracts
Bernoulli's principle(of lift) - faster moving air is lower air pressure
Air has a force called air pressure
Air is a fluid
Air is compressible, compressed air is higher pressure.
Air fuels combustion
