Chemistry: Intermolecular Forces and Gas Laws Quiz

Surface tension is the force acting in the surface of a liquid. It is measured in N/m.

As temperature increases, the speeds and kinetic energy of gas molecules also increase.

Avogadro’s law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
