Solids Versus Liquids


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


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


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


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.


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.
