When sugar is dissolved in water there is no increase in the volume which characteristics of matter is illustrated by this observation?

The observation that there is no increase in volume when sugar is dissolved in water illustrates the characteristics of matter known as "volume displacement" and "solubility." It demonstrates that when a solute (sugar) dissolves in a solvent (water), the solute molecules occupy spaces between the solvent molecules rather than adding to the overall volume. This behavior highlights the interactions at the molecular level and shows that the total volume of a solution can be less than the sum of the individual volumes of the solute and solvent.
