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 sealed syringe is plunged into cold water in which direction will the syringe piston slide?
Think about what happens to the gas (air) inside the syringe when the temperature decreases. As the gas cools it will occupy a smaller volume and thus the syringe plunger will move DOWN the barrel.
Why does it make sense that if you squeeze the air in a sealed syringe that the pressure will go up?
If you squash something in a sealed container then you are reducing the volume available for it to fit into and the result is that it pushes back (the pressure goes up). It is like forcing air into a bicycle tyre with a pump.
Does atmospheric pressure act on both sides of the plunger in the sealed syringe?
Yes, atmospheric pressure acts on both sides of the plunger in a sealed syringe. The pressure outside the syringe applies force on the outer surface, while the pressure inside the syringe is influenced by the contents within. If the plunger is pushed or pulled, the pressure difference between the inside and outside can create a force that moves the plunger. However, in a sealed environment, the pressure inside can change based on the volume of the fluid inside the syringe.
How does air pressure help in pulling medicine from syringe?
Air pressure helps in pulling medicine from a syringe by creating a difference in pressure between the inside of the syringe and the atmosphere outside. When the plunger is pulled back, it increases the volume inside the syringe, reducing the pressure. This lower pressure allows the higher atmospheric pressure to push the liquid medicine into the syringe, facilitating the withdrawal of the medication. Essentially, the pressure gradient created by the plunger movement enables the liquid to flow into the syringe easily.
How does a syringe help explain pressure and air pressure?
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.
Why can oxygen gas in a syringe be compressed to a smaller volume?
Oxygen gas in a syringe can be compressed to a smaller volume because gases are highly compressible compared to liquids and solids. When the volume of the syringe is reduced, the gas molecules are forced closer together, leading to an increase in pressure and a decrease in volume.
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.
If a capped syringe is heated in which direction will the syringe plunger move?
The fluid or gas inside the syringe will decrease in temperature, therefore it will decrease in volume. This will cause the syringe piston to slide inside the syringe. This is because of the ideal gas law: PV=nRT. If the pressure (P), the number of moles (n), and the ideal gas constant (R) remains constant, than the change in volume must be proportional to the change in temperature.
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.
Why would you not be able to continue decreasing the volume of a syringe until the volume was zero?
If the volume is zero, then there is no volume left in the syringe to measure.
If a sealed syringe is plunged into cold water in which direction will the syringe piston slide?
Think about what happens to the gas (air) inside the syringe when the temperature decreases. As the gas cools it will occupy a smaller volume and thus the syringe plunger will move DOWN the barrel.
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.
Why does it make sense that if you squeeze the air in a sealed syringe that the pressure will go up?
If you squash something in a sealed container then you are reducing the volume available for it to fit into and the result is that it pushes back (the pressure goes up). It is like forcing air into a bicycle tyre with a pump.

However, in a sealed environment, the pressure inside can change based on the volume of the fluid inside the syringe.
How does a syringe use atmospheric pressure?
Oh, dude, it's like this: when you pull back the plunger on a syringe, you decrease the pressure inside, creating a pressure difference with the atmosphere. So, the higher pressure outside pushes the liquid or medication into the syringe. It's basically like nature's way of helping you get that flu shot without even thinking about it.
If the air inside a balloon is heated the volume will?
If the air inside a balloon is heated, the volume will increase because the molecules move faster and spread out, causing the air to expand. Conversely, if the air inside a balloon is cooled, the volume will decrease as the molecules slow down and come closer together.
