The quantities that are greater for the substance in the gas phase compared to the liquid phase are:

II. Root mean square speed of the molecules: In the gas phase, molecules have more kinetic energy and thus move faster on average than in the liquid phase.

III. Average distance between the molecules: In the gas phase, molecules are more spread out and thus the average distance between them is greater than in the liquid phase.

I. Total intermolecular potential energy: This is a bit tricky. While individual molecules may have more kinetic energy in the gas phase, the total intermolecular potential energy is actually less. This is because in the liquid phase, molecules are closer together and thus have stronger intermolecular forces (which contribute to potential energy). When a substance is vaporized, these forces are overcome, reducing the total intermolecular potential energy. So, this quantity is not greater in the gas phase.
