To prevent injecting an air bubble into your blood, which can kill you.
An air bubble in a syringe can be injected into a vein, in which case it can cause an "embolus" or blockage. If the bubble gets stuck in the heart, it can cause a heart attack; an embolus in the brain causes a stroke. Either can kill within moments.
Appliances that work on air pressure: 1. Syringe Explanation: When the piston of the syringe is pulled, the volume in it increases, while the number of air molecules is still the same, resulting the low air pressure in the syringe and automatically, the air pressure outside is higher if compared to that of the air pressure in the syringe. the higher air pressure outside will force the liquid that you wish to suck to enter the syringe. 2. Siphon (for cleaning water in the aquarium) 3. Spraying pump 4. Straw All of the appliances work according to the same principle.
This is the effect of the pressure.
A syringe is similar to a balloon in effect on pressure. The more air you insert, the less space for fluid. The more pressure exerted on it, the less volume of air and the more the liquid would fill up the space.
Answersoap does float if it is filled with air
to avoid loss of drug as , after complete injection the air bubble remain inside the needle, not the drug
when you push the plunger are the air particles closer together in the syringe or in the bubble

The mass in the syringe, as you push down the plunger.
When injected into a vein, the air bubble(s) can cut off circulation to any blood vessel smaller than it.

Tapping a syringe causes any air bubbles to collect at the highest point in the syringe, and usually done when pointing it upwards. This makes removing air bubbles easier, which makes the syringe's use safer.
A water bubble is made of air. If you remove the air from it it will not be a bubble anymore.
Depends on the size of the air bubble, your body will absorb air that comes into the vein, but if the bubble is too big it cannot be absorbed and if it reaches your heart you will die. There is a practice called 'Packing testosterone'. Body builders who inject testosterone will actually put a small air bubble in the syringe which helps pack the testosterone into the muscle for optimum performance. This however is a very small amount. A little air in the vein is fine. This is something that you should never try alone, heck I wouldn't try it period lol! There are some cases where at the hospital and they put in the IV there is bubbles that will get in the line, this is perfectly fine because your blood absorbs it quickly. A syringe full of air injected into your vein would most likely get pumped to your heart and cause a massive heart attack.
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
The level contains a bubble of air.
yes you can, because the molecules of the air are loosely packed enough to be compacted or moved.
