Physical Properties of Gases

APCHEM-IEJLE8

Which of the following accounts for why physical properties do not differ much among gaseous compounds?

A

Gases only exist at high temperatures, resulting in a different set of properties from liquids and solids.

B

Gases are only found in non-polar covalent compounds, so there is no dipole moment that would allow for variations in properties.

C

Gases are only low molar mass substances, which means the low density results in a small variation of physical properties.

D

The relative distance between gas molecules is so large that there are virtually no intermolecular forces, resulting in little variation in physical properties.
