Defination :-
The force exerted by the atmosphere on unit area is called atmospheric pressure.
Examples :-
» when we fill the air in a balloon, The balloon inflates due to the pressure of the air inside it. If you fill too much air in the balloon , the balloon will brust, because the pressure on the walls of the balloon will increase beyond which it's walls can withstand. Air exerts pressure in both upwards and downwards direction.
» We drink cold drinks with the help of a straw. this is also based on air pressure, when you suck a straw, you swallow some of the air from the straw. This makes the pressure of air inside the straw less than the pressure of the air outside, so, the outside air pushes the cold drink into the straw.
» Doctors use syringe for injections. The medicine in the syringe is also filled due to air pressure when we push the piston of the syringe inside, air is pushed out through the narrow hole in the needle. when we put the needle in the liquid medicine and pull the handle outside, air pressure pushes the medicine into the syringe.
» Air exerts pressure and push the things. The sail boat moves because of air pressure. Wind Mill and flying kite are also of the common examples.
» we can set up a fountain by making use of air pressure. take a big bottle , fit it with a stopper and make two holes on the stopper. Put a straight and a long glass tube in a hole. the upper end of the tube should have narrow mouth. put a bent glass tube in the second hole. Now, put some water in bottle. The end of the straight tube should dip in the water and that of bent tube should remain outside the water. put the stopper and make it air tight . now blow air through the bent tube.
when we blow air through bent tube, the pressure inside the bottle increases. This pushes the water to rise through the second tube. It comes out in the form of a fountain.
