Explain pressure and its applications.
Answers
Answer:
The pressure of the liquid (blood) forces the liquid to move into the syringe when its plunger is withdrawn.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.
Answer:
The amount of force exerted (thrust) on a surface per unit area is defined as ‘Pressure’. It can also be defined as the ratio of the force to the area (over which the force is acting).
1.Air pressure in car tire supports the weight of the car.
2.Sucking a drink through a straw - fluid flows because of pressure difference.
3.Aircraft fly because of the air pressure on the wings.
4. Bullet fired from a gun is driven by gas pressure.
5. Toy balloon inflates because of air pressure inside.
