The displacement of air occurs in ventilation systems when cooled air fro the floor level is then redirected to the ceiling to keep rooms cool or the occupied zone. These air condition units help keep the population comfortable.
It's just the complement to fuel displacement. How much air the engine takes in affects how much fuel it can burn.
Example: double displacement reaction.
clouds
Hurricanes take place in water, but it also takes place in the atmosphere when hot air meets cold air.
Convection takes place because cool air is less dense than warm air.
alveoli
This is because condensation takes place after the compressor has compress the air in it.
The water displacement method is a way of measuring how much volume an object takes up. You fill a container with water, place the object in the water, and observe how much the water level rises.
Air enters or leaves your lungs.
combustion
Yes, when you fill a balloon with air, you are displacing the air that was originally inside the balloon with the new air. This is an example of the principle of displacement.
A very interesting event takes place at Cape Canaveral. It is the place where NASA launches rockets into outer space.
