Write five applications of pressure
Answers
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.
Applications of pressure:-
1) A syringe consists of a tight-fitting piston which moves in a cylinder, with a nozzle at one end also works with the help pressure.
2)When air is sucked out of a drinking straw ,the air pressure inside it decreases and the atmospheric pressure outside forces the liquid to go inside the straw.
3)A vacuum cleaner has a fan inside that creates a low pressure inside the device . Consequently,air and dirt particles are sucked into the device.
4)Siphon is only a rubber cylinder utilised for exchange fluid with the help of pressure.
