Question

15 examples of atmospheric pressure in our daily life​ with explanation

Answer 1

Answer:

Syringes are used to take blood for blood tests. The pressure of the liquid (blood) forces the liquid to move into the syringe when its plunger is withdrawn. When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.

When bulb is pressed, air present in tube and bulb escapes in the form of bubbles. However, there is atmospheric pressure on surface of liquid. When we release the bulb, the water moves inside the tube.
