Not sure what you mean by an F12 bulb. The number on a bulb F12T12 means 12 watt fluorescent and the T12 means 12 units of 1/8" diameter. So a T12 is 1.5 inches in diameter.
"Quicksilver" is an older name for the element mercury, which is used in fluorescent tubes. The average Compact Fluorescent Tube (CFT) contains 4 mg Hg. By comparison the old 48" tube contains 10-25 mg Hg in vapour and liquid form.
Parts of a stem are tubes and covering
None or a negligible effect. Similarly to incandescent or fluorescent tubes, they light up your work area so you can see what you're doing at the computer.
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.
The reason the water levels in the various manometer tubes are different is because of the difference in pressure. A manometer is used to measure the pressure between two different systems.
There is no difference. CFL is an abbreviation for Compact Fluorescent Light which has simply been designed to take up less space than the standard tubes.
I will assume you mean fluorescent tubes They are different caps
No.
"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
Yes they are interchangeable but the barrels however are not.

A pin based fluorescent light fixture is the type of fixture that takes fluorescent tubes. On each end of the fluorescent tubes there are contact pins. These pins are used to hold the tube in the fixture and to supply the voltage to the tube from the fixture's ballast.
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
The starter tubes are one inch longer than the towing tubes and do not have holes in them
I think that you may be confusing fluorescent tubes with neon tubes. Fluorescent tubes use a phosphor coating on the inside of the lamp which is in a limited spectrum. Some tubes are cool white, warm white, and daylight. There is also a gro lux which is on the warm end of the spectrum used for growing indoor plants.
sterilizations of equipment and the fluorescent tubes
Yes possible
