Question

According to kinetic molecular theory, attractions between particles do not influence the properties of which of the following states of matter?

Gases only

Solids only

Solids and liquids

Liquids and gases

Answer 1

Solids and liquids. This is because the attraction within solids are strong, the same can be said for liquids.... What if you exhale a bunch of CO2 on aluminum foil or what happens if you do the same to water in a glass? Not much- and nothing on the molecular level. What if you exhale into a partially filled helium balloon? It wouldn't float quite as well. The more co2 you mix with He the less the He would work against gravity- because of it's bonding.

Answer 2

it's gases, for the exact opposite reasons. In liquids and solids, the particles are generally packed closely together, so their mutual attractions will be very significant. Only gases are spread out enough so that the interactions of two random gas molecules will be insignificant to the properties of the gas as a whole
