Question

Give me one application of atmospheric pressure ​

Answer 1

$\mathfrak{\large{\underline{\underline{Answer :-}}}}$

What is Atmospheric Pressure ?

• Atmosphere is the gaseous envelope surrounding the Earth Due to mass the atmosphere exerts a force on the Earth's surface.

• The force exerted by the Earth's atmosphere per unit area of the Earth's surface is called atmospheric pressure.

$\rule{300}{1.5}$

Applications of Atmospheric Pressure :-

✰ $\textbf{\underline{\underline{Drinking straw - }}}$

• We normally use a drinking straw to suck up fruit juice.

• When we suck air at the upper end of the straw with our mouth the pressure of the air inside the straw is reduced.

• But the pressure acting on the surface of the fruit juice is equal to the atmospheric pressure, so the greater atmospheric pressure acting on the surface of the fruit juice pushes the fruit juice up the straw into your mouth.

✰ $\textbf{\underline{\underline{Syringe -}}}$

• When the nozzle of a syringe is dipped in a liquid and its piston is withdrawn, the pressure inside the syringe is lowered.

• The greater atmospheric pressure acting on is used the surface of the liquid pushes the liquid up into the syringe.

Answer 2

Atmospheric pressure is defined as the force per unit area exerted by the weight of the air.

Application of Atmospheric pressure ---

When we suck a fluid using a straw, the air inside the straw is removed, which leaves a low pressure area inside it. When the pressure of the surrounding (atmospheric pressure) is higher than the pressure inside the straw, it will push the fluid towards the inside of the straw, by this the fluid will eventually reach our mouth.
