Sugar dissolves in water because intermolecular connections between the slightly polar sucrose molecules and the polar water molecules release energy.

The energy required to destabilize the structure of both the pure solute and solvent is made up for by the weak bonds that develop between the solute and the solvent. The sugar molecules occupy the space between the water molecules when the sugar dissolves in the liquid. They therefore don't take up any additional space. So the solution's volume stays the same. Because hot water has more energy than cold water, sugar dissolves more quickly in hot water than it does in cold water. When water is heated, the molecules become more energetic and travel more quickly.

Because of the energy released during intermolecular interactions between the polar water molecules and the slightly polar sucrose molecules, sugar dissolves in water.

The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and solvent. When sugar dissolves in a liquid, the sugar molecules take up the space between the water molecules. As a result, they don't contribute any extra room. Thus, the volume of the solution does not change. Sugar dissolves more quickly in hot water than it does in cold water because hot water has more energy. The molecules of water move more swiftly and energetically when it is heated.
