Is dissolving sugar in water a physical change or a chemical change?

Dissolving sugar in water is a physical change because it does not result in the formation of new substances. When sugar dissolves, the sugar molecules disperse throughout the water, but they retain their chemical composition. This process is reversible, as evaporating the water would leave the sugar behind. The individual sugar molecules are still intact, only separated and spread out within the water. This change in the physical state of sugar does not alter its molecular structure, indicating that it is a physical change, not a chemical one.
