How does the density of gases compare with that of liquids and solids?

Answer 1

Density is the amount of matter in a given volume. The particles in a solid state are tightly packed together, therefore a solid sate would have a greater density then a liquid, and gas. The particles in a liquid state are together, but are able to move and slide by one another. This density is not as great as a solid state. Particles in a gaseous state are spread very far apart, and moving a lot. A gas would not have a large density. The particle theory of matter affects both masse, volume, density, and viscosity.

Answer 2

As a whole, solids are denser than liquids. Of course there are exceptions but that is a general rule you should follow.

If you're having trouble remembering this, then just think of the relative densities of a solid and a gas. Everybody knows that a solid is more dense than a gas right? Well liquid is right between them in terms of physical structure so it makes sense that the solid is in turn more dense than a liquid.

Hope that helps :) First answer I've posted :P

Answer 3

Yes, density just refers to the substance itself, it has nothing to do with the medium it is surrounded by.

Answer 4

The density of air is significantly lower.

Answer 5

The density of air - or most gases - is much less than the density of typical solids and liquids.

Answer 6

Gases have lower densities.
