Explanation:
To fill medicine in a syringe, air pressure is required. This is because of the way a syringe works. A syringe consists of a barrel, a plunger, and a needle. The barrel is a hollow tube that can hold the medicine. The plunger is a long, narrow rod that fits inside the barrel and can move back and forth. The needle is a thin, pointed metal tube that is attached to the end of the barrel.
When the plunger is pulled back, it creates a vacuum inside the barrel. This means that there is a low pressure inside the barrel, which causes the medicine to be drawn into the syringe. The air pressure outside the syringe is higher than the pressure inside the barrel, so the medicine is pushed into the barrel.
When the plunger is pushed forward, it pushes the medicine out of the syringe through the needle. The air pressure inside the barrel is higher than the pressure outside the syringe, so the medicine is forced out of the needle.
In summary, air pressure is required to fill medicine in a syringe because it creates a vacuum inside the barrel, which draws the medicine in. When the plunger is pushed forward, the air pressure inside the barrel forces the medicine out of the needle.

The air pressure plays an important role in the filling of a syringe as the liquid medicine rushes into the syringe when the air pressure inside it decreases on pulling the piston out.
