A syringe demonstrates the relationship between pressure and volume. When you pull the plunger, the volume inside the syringe increases, causing the pressure to decrease. This is because the air particles inside the syringe become more spread out, resulting in lower pressure.

What happen if you push down on the plunger of a syringe filled with air?
If you push down on the plunger of a syringe filled with air, the air inside the syringe will be compressed and the pressure will increase. Depending on how much force you apply, the air may be expelled through the needle if the pressure exceeds what the syringe can hold.
What happens to the air particles when you pull the syringe plunger back up after pushing it down?
When you pull the syringe plunger back up, the volume inside the syringe increases, causing the air pressure to decrease. As a result, the air particles inside the syringe spread out to fill the newly available space, creating a lower pressure environment.
What is the effect on the volume of the air in the syringe if more force is exerted on the plunger?
Increasing the force on the plunger will decrease the volume of air in the syringe as the increased pressure compresses the air.
What causes the air pressure inside the push syringe to increase?
The plunger being pushed into the syringe compresses the air inside, reducing its volume and increasing its pressure. This is due to Boyle's Law, which states that pressure and volume are inversely proportional at constant temperature.
What are similar experiments to air pressure with an egg?
Two similar experiments to air pressure with an egg include using a balloon and a plastic bottle or a syringe and a cup of water to demonstrate effects of air pressure changes on objects. These experiments can show how changes in air pressure can cause objects to move or be affected in different ways.

Increasing the force on the plunger will decrease the volume of air in the syringe as the increased pressure compresses the air.
Why the volume of the air molecules inside of the syringe changes?
This is the effect of the pressure.
What is the device to air pressure?
A barometer is a device used to measure air pressure. It works by balancing the weight of the atmosphere with a column of liquid (such as mercury or water) in a closed tube. The height of the liquid column is directly related to the air pressure.
What happens to the volume of air in the syringe?
A syringe is similar to a balloon in effect on pressure. The more air you insert, the less space for fluid. The more pressure exerted on it, the less volume of air and the more the liquid would fill up the space.
What causes the air pressure inside the push syringe to increase?
The plunger being pushed into the syringe compresses the air inside, reducing its volume and increasing its pressure. This is due to Boyle's Law, which states that pressure and volume are inversely proportional at constant temperature.
How does a syringe use atmospheric pressure?
A syringe uses atmospheric pressure to push the liquid medication out of the barrel when the plunger is depressed. When the plunger is pulled back, it creates a vacuum, causing the liquid to be drawn into the syringe due to the atmospheric pressure pushing down on the liquid outside the syringe.
Why does a syringe plunger go back in if you pull it out?
When the plunger is pulled, the volume inside increases. This reduces the pressure inside, and the air pressure outside forces liquid in, in an effort to make the pressure inside and outside the syringe equal again.
If a capped syringe is heated in which direction will the syringe plunger move?
When a capped syringe is heated, the air inside the syringe expands due to the increase in temperature. This expansion of air will create pressure inside the syringe, causing the syringe plunger to move outwards.
What is a hot air ballons air pressure?
The hot air balloons air pressure is usually used to explain the principle of buoyancy.
How can an air bubble be expelled from a syringe?
To expel an air bubble from a syringe, first hold the syringe with the needle pointing up. Then gently tap the side of the syringe to move the air bubble towards the needle. Finally, push the plunger slowly to expel the air bubble out of the syringe.
