Question

How would you demonstrate the presence of atmospheric pressure?

Answer 1

Atmospheric pressure is a pressure that is the column of air above every matter. We can demonstrate the presence of air by doing some experiments or by feeling the atmospheric pressure in our daily life situations

Answer 2

Answer:

• The ‘presence of atmospheric pressure’ has been demonstrated by the cardboard water cover experiment.
• When the glass with water and covered with a piece of cardboard is inverted, we can see that the cardboard cover does not fall and water remains inside the glass even after the hand is removed.
• This is due to the atmospheric pressure that acts on the cardboard from outside is greater than the force exerted by the weight of the water present in the glass.  

• Atmospheric pressure is the pressure exerted by  atmospheric weight.
• The presence of atmospheric pressure can also be proved by the crushing can experiment, Magdeburg Hemisphere and by many other methods.
