Answer_____♥️
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.
