Application of pressure in syringes
Answers
Answer:
The syringe works on the existence of atmospheric pressure. When the nozzle of a syringe is dipped in a liquid and its piston is withdrawn, the pressure inside the syringe is lower. The greater atmospheric pressure acting on the surface of the liquid pushes the liquid up into the syringe.
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.
