Molecular volume refers to the space occupied by a single molecule of a substance, which is crucial for understanding the physical properties and behavior of substances in different states of matter. It is determined by the size and shape of the molecule, as well as the intermolecular forces acting upon it.

Physical properties of substances are characteristics that can be observed or measured without changing the substance's chemical identity, providing essential information for identifying and classifying materials. These properties include aspects like density, melting point, boiling point, and solubility, which are crucial for understanding material behavior under different conditions.

Intermolecular forces are the forces of attraction or repulsion between neighboring molecules, crucial for determining the physical properties of substances such as boiling and melting points. These forces, while weaker than intramolecular forces (bonds within molecules), play a significant role in the behavior of liquids, solids, and gases.
