Air pressure

Air pressure

The Earth is surrounded by a layer of air known as the Earth's atmosphere. Air consists of particles that are always moving freely in all directions and collide with the walls of the environment or walls of the container.

Air Pressure

	Air pressure results from the collision of air particles on the surface of an object

The relationship between air pressure and altitude

Air pressure varies from place to place
The air pressure at the top of the mountain is lower than the air pressure at the foot of the mountain
Air pressure decreases when at a higher altitude
The number of air particles decreases when being in a higher position

Air Pressure Application

When air is inhaled, the area inside the straw creates a low pressure area. The higher air pressure outside will push the water into the straw.

When the plunger is pressed, there is low pressure inside the plunger and causes the air in the plunger to come out. The higher pressure in the sinkhole pushes out the clogged waste when the plunger is pulled up.
