So that there wouldnt be any air in the syringe. because if just a little bit of air is injected into your body, you'll die

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)


How do you draw 1.1 ml on a syringe?

To draw 1.1 ml on a syringe, first ensure the syringe is clean and properly calibrated. Pull back the plunger to the 1.1 ml mark, ensuring there are no air bubbles in the barrel. Insert the needle into the liquid and push the plunger slightly to expel any air, then pull back the plunger to the 1.1 ml mark again if necessary. Finally, remove the needle from the liquid and check the measurement before using it.


What type of pressure is involved in the filling of a liquid in a syringe?

In the filling of a liquid in a syringe, atmospheric pressure plays a role in pushing the liquid into the syringe barrel when the plunger is pulled back. This pressure difference helps create the suction needed to draw the liquid into the syringe.


How do you draw up 0.7 ml on a 3 ml syringe?

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.


What did you observe when you tried to push the plunger of the syringe while your hand was pressing against its end?

When pushing the plunger of the syringe while my hand was pressing against its end, I noticed that the resistance was significantly increased. This resistance occurred because the pressure applied at the end of the syringe was transmitted through the liquid inside, making it harder to push the plunger.


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.


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.


When reading a syringe one reads the calibrated scale that directly lines up with the?

plunger's tip to accurately measure the volume of liquid being dispensed or drawn into the syringe. The measurement is typically indicated in milliliters and should be read at eye level for precision.


What is 0.34 ml on a syringe?

0.34 ml on a syringe represents 34 units on the syringe's scale. To measure it, draw the plunger up until the liquid reaches the 0.34 ml mark on the syringe.


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.


When you place your finger on the plunger of a syringe containing some water it does not depress noticeably?

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


What is one example of Boyle's law in action?

An example of Boyle's law in action is when you use a syringe to draw liquid medication. As you pull back the plunger, the volume inside the syringe increases, causing the pressure to decrease according to Boyle's law.
