Dissolving sugar is a common phenomenon that raises the question: is it a chemical change? To explore this topic, we can examine four key entities: sugar, water, solute, and solvent. Sugar, a crystalline substance, dissolves in water, a liquid solvent. During this process, sugar molecules disperse into water molecules, forming a solution. However, this dissolution does not result in the formation of new substances or the breaking of chemical bonds, indicating that the process is likely a physical change rather than a chemical change.
