Question

explain with an activity that air around us exert pressure​

Answer 1

Hey mate,

Air pressure can be understood with the help of certain activities.

Activity I

• Materials Required: tumbler, water, square cardboard piece

• Method: Fill up the tumbler with water up to the brim. Cover it with cardboard piece and turn the glass upside down. Slowly remove your hand.

• Observation: Cardboard does not fall and water stays in the glass.

• Inference: air pushes the cardboard up and prevents it from falling.

Activity II

• Materials Required: Two balloons

• Method: Blow the balloons and tie string to it. Hang them 10 – 12 cm apart on a rim. Blow air in between the balloons.

• Observation: The balloons will move closer.

• Inference: The air pressure between the balloons is reduced due to more speed. Air moves from higher pressure to lower pressure bringing the balloons closer.
