The gases were mixed so it went up
The reaction between citric acid and sodium bicarbonate produces carbon dioxide gas. The formation of gas bubbles causes pressure to build up inside the syringe, pushing the plunger upward. This upward movement is a result of the gas expanding and creating a force against the plunger.
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.
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
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.
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.
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
A gas syringe is basically a device that fills up with a gas that is produced and gives a volume for that gas. Gas from a reaction is forced into the syringe due to pressure and the syringe plunger is forced out (just like how you suck up a liquid with a normal syringe). It can be used to detect the volume of gas produced in a chemical reaction for instance.See the Web Links to the left for more information.
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
