3 applications of pressure
Answers
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 The pressure of the liquid (blood) forces the liquid to move into the syringe when its plunger is withdrawn.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

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.
