The answer depends on your definition of "small". A raindrop, for example, would be measured in millilitres (a thousandth of a litre). High quality ink-jet printers measure the amount of ink released in picolitres (trillionths of a litre).
Volume, usually liquids.
yes
No, small amounts of liquids do not fill a large container. The volume of the liquid stays the same, regardless of the size of the container it is placed in.
The use is to accurately measure small amounts of liquids and powders
It measures small amounts of liquids.
Only if the solid is in the form of a fine powder. Alternatively, if the solid is small and you have a liquid in which it is not soluble, then it is possible to employ the displacement method to measure its volume.
Measuring liquid.
a lighter or or burner.
The correct term for the laboratory tool used for transferring small amounts of liquid is "pipette."
You call a very small drop of liquid a 'droplet'. A droplet is a smaller measurement of a drop of liquid and is usually used when talking about liquid particles that are less then 50 um in diameter.
That means how easy it is to compress the liquid - to reduce its volume by applying pressure. Liquids are normally not very compressible.
