Air & Aerodynamics pt 2

What happens to the air molecules when air is compressed?

• The molecules pop

• Nothing

• The molecules can be squeezed closer together

• The molecules spread apart

What is the relationship between how much air has been compressed and air pressure?

• The less air pressure the more air pressure

• The more air is compressed the more air pressure

• The more air is compressed the less air pressure

• Their is no connection
