Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

The answer a way of explaining a complex concept.
Answer:
C. is less than 0
Explanation:
The Gibbs free energy (G) of a system is defined as the energy that is used for the work done. The change in Gibbs free energy during a reaction shows the spontaneity and energetics of the reactions.
A reaction will be spontaneous if the change in Gibbs free energy will be negative or less than 0. Reactions with positive Gibbs free energy are non-spontaneous.
Hence, the correct answer is "C. is less than 0".
