no it only depresses if you apply pressure. If the finger is just resting on it the liquid inside will remain there.

Can you push the plunger all way through the syringe while your thumb presses on the tip of the plunger why or why not?

No, you cannot push the plunger all the way through the syringe while your thumb presses on the tip of the plunger. This is because the plunger is designed to create a seal within the barrel of the syringe, and pressing on the tip prevents the plunger from moving forward. The pressure created by your thumb would counteract the force needed to push the plunger, making it impossible to fully depress it.


What happens when you depress a syringe?

When you depress a syringe, the plunger moves downward, creating increased pressure within the barrel. This pressure forces the fluid inside the syringe out through the opening, allowing it to be injected into a target area or system. The action of depressing the plunger also draws in any air or fluid from the back, depending on the syringe's position and usage. This process is commonly used in medical applications for injections or drawing blood.


What happens to the marshmallows in the syringe as i push the plunger down What happens to the marshmallows in the syringe as i pull the plunger up?

When you push the plunger of a syringe down into a marshmallow, it puffs up with air. When you pull the plunger of the syringe up while it is in the marshmallow, it will shrink.


What crumpled a plastic bubble in a syringe when you apply force to the plunger?

The mass in the syringe, as you push down the plunger.


When using a tuberculin syringe do you measure using the edge of the plunger where it touches the syringe or the tip of the rounded edge of the plunger?

Measure to the edge of the plunger (or piston) where it touches the inside of the syringe cylinder. http://www.northcumbriahealth.nhs.uk/palliativecare/clinical/syringe/05.php


How would you use a syringe to see if air was compressed?

To test if air is compressed using a syringe, pull the plunger out to create a vacuum inside the syringe. Then, push the plunger in quickly. If the air inside the syringe is compressed, you should feel resistance when trying to push the plunger in. If the air is not compressed, the plunger will move easily.


A doctor pushes down the plunger of the syringe places its nozzle in the medicine and then pulls up the plunger to make the medicine rise up in the syringe?

he pushes the plunger so that he removes the air molecules from the syringe and make it vacuum and then puts it in the medicine and pulls the plunger so that the liquid rises without the air molecules getting in the syringe (arjun)


When you push the plunger are the air particles closer together in the syringe or in the bubble?

when you push the plunger are the air particles closer together in the syringe or in the bubble


If you press the plunger on a syringe with gas in it what can you see inside the syringe?

When you press the plunger on a syringe containing gas, you may not see any visible changes in the gas itself since gases are generally not visible. However, you may notice the gas compressing, which could manifest as a decrease in volume or pressure inside the syringe. If the syringe is transparent, you might see the movement of the plunger and feel resistance as the gas molecules are forced closer together. If the gas is at a high pressure, you might also hear a sound as it escapes through any openings or valves.


Why must the plunger of a gas syringe be rotatated?

To ensure that the plunger can move and not stuck. Because if it is stuck, when the gas goes into the syringe, the plunger will not move back and so the values you received will be lower than the actual value


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.


If you push the plunger of a syringe filled with air and let go what will happen?

If you push the plunger of a syringe filled with air and let go, it will come back up again! :) :P
