Compare what you felt when you pushed the plunger with the air and with the water?

Sagot :

when the plunger of syringe was pushed you can feel the force pushing your finger that is covering the opening and when you stop pushing the plunger the syringe with air seemed to suck the skin of the finger that was covering the plunger it is because the air is producing some sort of a vacuum as it moves to occupy the whole space of the syringe, the vacuum production is not observed in syringe with water
