Question

What are the applications of atmospheric pressure?

Answer 1

Applications of atmospheric pressure:

1. Syringe: When the piston is pulled up, the atmospheric pressure inside the cylinder will decrease. The atmospheric pressure outside pushes the liquid up into the syringe.

2. Straw: When a person sucks through the straw, the pressure in the straw becomes low.
The atmospheric pressure outside which is higher will force the water into the straw and consequently into the mouth.
3. Vacuum cleaner: When a vacuum cleaner is switched on, it sucks out the air inside the cleaner, causing the pressure inside the cleaner to become low. The atmospheric pressure which is higher in magnitude forces the air and dust particles into the cleaner.
