How does a dropper work?
If you squeeze the bulb to expel most of the air, then release it with the tip under water, the pressure in the bulb drops and external air pressure on the surface of the liquid in its container forces the liquid into the dropper. When you squeeze the bulb again, you increase the pressure and force the liquid out.
Steps of measuring the medicine in the medicine dropper?
shake well, squeeze tip/bulb watch medicine fill tube, release bulb, notice med is at correct line, insert into proper orifice, squeeze bulb to discharge med. release bulb. remove.
Why the rubber bulb of the dropper must be pressed before the liquid rises to the dropper?
It is the expansion of the rubber bulb which draws the liquid upward, and it cannot expand if it is not first squeezed. Air pressure pushes liquid up into an expanding bulb since the expansion of the bulb, with no access for air to enter, creates a partial vacuum.
How does medicine enter in dropper?
It's commen sense actually,it's due to diff in air pressure by pressing it creates low pressure and outside is a gap higher pressure thus fluids movie from outside(high pressure to low pressure)to the inside of the dropper.
What is a dropper and what are its uses?
A dropper simply is a small tube with a air-filled bulb at the top. You squeeze the bulb at the top and whatever substance the tube is submerged in, it will be pulled up into the tube. After that, you lightly squeeze the bulb again to release the substance in the tube out.
How does the ink dropper works?
ink dropper works on the principal of air pressure. when we fill ink inside the dropper we have to press it's bulb(upper,soft rubber portion),because of which the air inside the dropper is removed and low air pressure region is formed. when we dip it in the ink,the space is filled with ink,which remains retained in it unless we press the bulb again.
What a eye dropper?
A glass or plastic pipette with a rubber bulb that is used to drop medicines into the eye.
What is pipette dropper?
It's also called a teat pipette or pastette. It's a glass or plastic tube with a narrow opening at the bottom and a flexible bulb at the top used for sucking up and transferring small volumes of liquid. We often use one for eye drops.

Is a light bulb a solid liquid or gas?
The bulb itself is a solid.
What is pipette made up of?
A pipette is either a glass or plastic narrow tube with a rubber bulb on one end. The idea is to put the open end into a liquid, after depressing the bulb. On releasing the bulb, a suction is formed and liquid is drawn up the tube. The pipette can then carry the liquid to another receptacle. On squeezing the bulb, the liquid is deposited into the new receptacle.
Why does the thermometer go down when cooled?
The cold reduces the temperature in the liquid inside the thermometer bulb. Most substances contract when their temperature drops so the liquid in the bulb occupies less space. this causes the column of liquid outside the bulb to become smaller.
