The molecules of a particular substance are identical, whether it is in the liquid or gaseous state. With reference to the molecules, give (i) one similarity and (ii) one difference between the molecules in liquid and gaseous states.

Similarity
Molecules move quickly in random directions in cases of liquids/gases as compared to solids and thus take the shape of the container.
Dissimilarity
The molecules are widely separated in gases as compared to liquids

Similarity: the structure of the molecule. H2O is a bent molecule, no matter what state it's in.
Difference: Distance between the molecules. In the liquid phase, the molecules are close together. In the gas phase, the molecules are far apart from each other.

the primary difference is the spacing. molecules in a gas are 1000x farther apart than in liquid.
another difference is their kinetic energy. molecules in a gas have much more kinetic energy. this is evidenced by the higher temperature of gases.

they (the molecules) are farther apart and moving faster

No it's not...it's a question that makes you look stupid
