Solids Versus Liquids

APCHEM-AGR2DN

Which of the following​ is TRUE regarding solids and liquids?

A

Liquids do not hold a fixed shape like solids do because the intermolecular forces between liquid molecules are less than those between solid molecules.

B

A collection of molecules can only change from a solid to a liquid or a liquid to a solid by a change in temperature.

C

By manipulating the pressure on solids and liquids, it is possible to have two substances exist in the solid phase at a temperature higher than their melting points.

D

The molar volume of a liquid will always be much greater than that of a solid because the liquid particles have enough energy to escape intermolecular attractions and not be held to a fixed shape.
