Like the number of cells in a brain, variable (and zero if the space or brain is empty).
Yes. Gases are very compressible because there is a lot of empty space between the molecules. A liquid has almost no empty space between the molecules. When compressing a gas you are pushing the molecules closer together, getting rid of some of the empty space. Can't do that with liquids. Example 18grams of liquid ware will occupy 18 ml or 0.018 Liter of space (volume). Boil that same 18 grams of water and it will occupy about 24000 ml or 24 Liters of space because in the gas form the same number of molecules are farther apart with lots of empty space between them .
molecules of a solid break up get's into the space that is in between the liquid molecules
Lots of space between the atoms and molecules.
yes
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
Molecules take up less space as they cool. The space contains more molecules.
It has a different amount of space between molecules.
Every particle has empty space or voids between each other called intermolecular or interparticle spaces......
No - just space. The space has no pockets.
Sounds vibrate the air molecules, when the vibrating molecules reach your ear, you ear the sound, there are no molecules in space, thus no sound in space

In order for sound to travel, there has to be something with molecules for it t travel through. On Earth, sound travels by vibrating air molecules, there are no molecules in space, nothing to vibrate
Molecular Spacing, is the space between molecules in an atom. :D
molecules and atoms
A vacuum
