Because hot water has low intermolecular force of attraction so they have high intermolecular space. As there is more space between their molecules and high kinetic energy due to heat, the hot water dissolves sugar crystals faster than the cold water.

The reason why sugar dissolves at a faster rate in hot water has to do with increased molecular motion. The added energy in the hot water causes water molecules to move faster and sucrose mol
ecules to vibrate faster. This added movement tends to make the bonds between sucrose molecules easier to overcome.
