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
Atmospheric pressure.
Absolutely. The most obvious examples are vaporization of a liquid when the pressure is lowered. For example, if you release the fuel in a disposable lighter, the liquid butane becomes a gas when it reaches the lower pressure of the atmosphere. You can demonstrate this with water by putting it in a syringe, closing the end, and rapidly pulling out the plunger. The water will actually bubble and boil at room temperature.
liquid
It evaporates.
yes because before you pour the concrete down it is a soft liquid................
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 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.
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.
no it only depresses if you apply pressure. If the finger is just resting on it the liquid inside will remain there.
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.
The easiest way to dissolve trimethoprim for oral administration is to drop the tablets into a 60cc syringe - pull the plunger out then drop the tablets into the body of the syringe. Put the plunger back in and depress it until the tablets can't rattle around. Fill a small glass with tap water, then pull water into the syringe. Place a fingertip over the tip of the syringe to seal it, then shake the syringe to get the tablets to dissolve. This may take a few minutes, and the resulting paste/gel/liquid is not going to taste good to your pet so expect to need some help restraining him/her to give the medication.
Dilute Equine Ponazuril paste for cats and dogs with water. To make a 50mg per ml solution mix 10ml paste to 20ml water. Make sure to mix/shake thoroughly. Easiest way I have found is to mix it in a large flushing syringe that holds 50ml. Remove the plunger from the syringe and put your finger over the smaller opening to keep the liquid from leaking out and from the top add warm water to the 20ml mark on the syringe and then squeeze paste into the syringe until the water level rises to 30ml. Carefully put the plunger back into the syringe with the open end up so nothing leaks out. Once the plunger is firmly in the syringe you can plug the other end again with your finger and shake vigorously to mix. Use it immediately. Usually dosage for puppies is 1ml of the mixed solution per kg (2.2 lbs) of body weight daily for 1-5 days. Can be repeated in 1 week if necessary.
All gasses and vapors are compressible, whereas liquids and solids are not compressible to any useful extent. The compressibility of gasses is due to the much greater spacing of its molecules than would exist in its liquid or solid state; in fact, if you compress a gas far enough, it will eventually become a liquid, and then a solid. The compressibility of gasses is a very useful property that allows us to run machinery and to make aerosol sprays.

The term syringe actually refers to the type of fluid that is in encased in the reservoir of the syringe. However, the function of a syringe is either to pull or push liquid from that reservoir.
The unknown liquid could have a low suface tension like may organic liquids. Also, the plunger of the pipet could be being pushed all the way down when extracting the liquid ( should be at first stop) so it leaks out before the transfer is complete. To avoid this, pipet some liquid in and blow it out by pushing the plunger all the way down (second stop). Then draw up some more of the liquid and it should not leak.
