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.
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.
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)
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.
When you push down on a syringe plunger, you compress the air or liquid inside, creating increased pressure. Once the plunger is released, the pressure inside the syringe decreases, allowing the plunger to return to its original position due to the force of the surrounding air pressure or liquid pushing back against it. This is an example of how pressure dynamics in a closed system work, causing the plunger to pop back up.
Pull the plunger of the syringe down to the 0.7 ml mark on the scale. Insert the needle into the liquid and slowly draw up the desired amount of 0.7 ml by gently pulling back on the plunger. Ensure no air bubbles are trapped in the syringe before administering the medication.
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.
The same way you read ANY syringe. From www.wikipedia.com (http://en.wikipedia.org/wiki/Syringes), if you click on the image of the 10ml syringe, you'll see the markings on the barrel. You measure the units of fluid from the needle side back to the plunger - so as you pull back the plunger you draw in "x" ml's of fluid as marked from the needle back. Standard safety procedures surrounding the use of a syringe should always be followed, and in no way is this short answer a full and complete explanation of how to correctly/safely use a syringe.
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.
To draw up 6.7 cc (cubic centimeters) of a liquid, first ensure you have the appropriate syringe calibrated in cc. Pull the plunger back to the 6.7 cc mark, then insert the needle into the liquid and push the plunger down to expel any air bubbles. After that, draw back the plunger slowly until the liquid reaches the 6.7 cc mark. Finally, check for air bubbles again before removing the syringe from the vial.
It works kinda like a syringe. Make sure the plunger is all the way down then submerse the other end in a cup of water then pull up on the plunger. You're now ready to squirt people
You shouldn't do that. Its sounds dangerous
