when a sugar cube dissolves in water, it becomes a solution of sugar and water. a solution can be said to be a homegenous mixture of the water and sugar molecules.

in order for this to happen, the sugar cube molecules have to become free from each other to mix freely with the water molecules. this requires energy, since the bonds between the molecules in the sugar cube have to be broken. since hot water has more energy than normal water, it is easier for the sugar cube to dissolve.
