Question

how does a dropper work to fill ink inside it ?

Answer 1

Answer:

Hey mate

Here is your answer ^_^

When you squeeze the rubber top on the dropper you squeeze the air out.Then when you put the tip into the liquid and stop squeezing the top,the low pressure inside sucks up the liquid....The liquid is held in by the low pressure in the tube than the external atmospheric pressure.

Hope it helps.If yes pls...leave a thanks.

Answer 2

Answer:

when u squeeze the rubber top on the dropper u squeeze the air out then when u put the tip into the liquid and stop squeezing the top, the low pressure inside sucks up the liquid. in fact it is the higher pressure outside the dropper in the liquid, that pushes the liquid up into the dropper.
