Okay wait
oh...thank you sooooooo much
Here are they explained.. I will send h in inbox ok
---> It pains wearing thin strapped bags because of more pressure.That's why it is preffered to use bags having thick strpaes.
----> Massage is one type of application of pressure. By doing this it reflexes the feet, hands, ears and their referral areas within zone related areas, which correspond to every part, gland and organ of the body. This is because while giving pressure it pushes the nerves and we don’t get any pain later.
--->
When we pull the plunger out on a syringe it causes the volume within the chamber to increase. As we know, this causes the pressure do the opposite, which creates a vacuum attempting to re-pressurize back to atmospheric levels. Since the only fluid available on the other side of the needle tends to be a liquid such as blood, which gets sucked into the chamber, reducing the volume and increasing the pressure back to where it wants to be.

--->The ink dropper that we use almost on a daily basis actually works on the air pressure principle. As soon we create a low pressure by removing the air inside the bulb, the ink flows in to fill in the void.
---> An aeroplane would take off from the ground based completely on the fact that when we cause the air to move we lessen the air pressure in the immediate surrounding and that helps in lifting the aeroplane.
Hafff...This much is okay..Tired of typing and thinking
thank you very much

1. Air pressure in the car tyre which supports the weight of the car.
2. Aircraft fly because of the air pressure on the wings.
3. Toy balloon is filled with air which gives pressure to the inner walls of the balloon.
4. Sucking a drink through a straw - the difference in the pressure causes the liquid to flow.
5. Bullet fired from a gun is driven by gas pressure.
