Molecules take up less space as they cool. The space contains more molecules.
Heated molecules causes molecules to bounce into each other separating them. As molecules separate, their density, the amount of matter found in a given volume or space, decreases. Cooled molecules are not that loose and start to get packed together if it gets frozen. -twocute
Space between the molecules.
That's a 'vacuum'.
If molecules are outer space, they have no forces (gravity) to move them around, hence that is why they stay togethor i.e. in a structural arrangement of a solid state.
equilibrium because the concentration of molecules will be the same throughout the space the molecules occupy.
The absence of air molecules to transmit and carry sound waves .
equilibrium QUEENSCENE: yes, equilibrium because the concentration of molecules will be the same throughout the space the molecules occupy.
No, the absence of matter would be a vacuum, which is quite different from a black hole. A regular black hole has a fairly large amount of mass (which is basically the same as matter) in a small space.
"Space" is one those things like 'cold', 'silence', and 'emptiness', that isn't 'something' all by itself. It's just the absence of something. Silence is the absence of any sound. Cold is the absence of any heat. Space is the absence of any material.

A shadow doesn't exist as a thing. It doesn't take up space or have mass. It's just the absence of light or brightness in a given area.

Density is the ratio between the mass and volume, at a given temperature.
It has a different amount of space between molecules.
No.
A gas is one of the phases of matter. It is mainly composed of molecules that are constantly moving around in random directions, with the tendency to fill any available space.
