Question

describe the working mechanism of syringe with diagram​

Answer 1

Answer:

A syringe is a pump consisting of a sliding plunger that fits tightly in a tube. The plunger can be pulled and pushed inside the precise cylindrical tube, or barrel, letting the syringe draw in or expel a liquid or gas through an orifice at the open end of the tube.

Answer 2

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 When the nozzle of a syringe is dipped in a liquid and its piston is withdrawn, the pressure inside the syringe is lower.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.
