Question

Applications based on Pressure and Atmospheric Pressure

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

Two applications of atmospheric pressure :

• Straw : When a man sucks up the fluid from straw the pressure inside is moderately low and accordingly atmospheric pressure outside powers up the fluid into straw.
• Vacuum cleaner : When a vacuum cleaner is exchanged on, the pressure inside tumble off because of air inside.

Applications of Pressure in Daily Life :

• The area of the edge of a knife's blade is extremely small.
• Syringes are used to take blood for blood tests.
• When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.
