Question

Give three points of everyday experience which prove that air exerts pressure

Answer 1

Answer:

1) You can drink from a straw.

2) Balloons hold their shape.

Answer 2

Answer:

1.The higher we go the less amount of pressure is exerted on us (our body's and object's pressure increases) that is why plastic bottles in a mountaineers backpack are crushed when the mountaineer approaches higher altitude

2.Mountain Climbers have nose bleeds while climbing the mountain because at altitude, Pressure inside our body is greater than the surroundings

3.car window mats stick onto any smooth surfaces, the pressure applied by the car window mat squeezes out most of the air trapped inside, the large atmospheric pressure acting on the car window mats from the outside also enables the car window mat to firmly stick onto the surface

thank you! and God bless you!!
