Question

Do gases have high or low densities?

Answer 1

Gases typically have exceptionally low densities.

Explanation:

`"Density, "rho="Mass"/"Volume"`. It is well-known that a gas will uniformly occupy (i.e. expand to fill evenly) whatever volume is available to it.

On the other hand, solids and liquids, condensed phases, are high density materials where `rho` is relatively constant.
