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.
The mass in the syringe, as you push down 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
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.
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
Rotating the plunger of a gas syringe ensures that there are no air bubbles trapped inside which can affect the accuracy of the measurement. It also helps to create a seal between the syringe and the gas being measured.
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, it will come back up again! :) :P
No, it is not recommended to push the plunger all the way through the syringe while your thumb is pressing on the tip. This can cause the plunger to come out of the syringe barrel unexpectedly, potentially leading to spillage of the contents or injury. It's better to use the syringe as intended for safe and effective administration.
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.
The pressure generated by a syringe is a result of how hard the plunger is pushed and the internal diameter of the needle, not the size of the syringe.
