It dissolves
Dissolution is a physical process.
The "cube" disappears but the "sugar" doesn't. When placed in water the sugar dissolves. Essentially the sugar molecules break off from the solid and hide among the water molecules. If the water were to be removed by evaporation the sugar would precipitate out. if done carefully large sugar crystals will grow in the evaporating solution. The sugar cube will not reform as this is an artificial construct.
Sugar dissolves in water.
using diffusion what might happen when you drop a sugar cube into a mug of tea. For the sugar cube ,since the sugar cube is source, the molecules will diffuse into the hot water the sugar cube will despair
i think its cos the sugar cube releases the oxygen that has been trapped inside it when it dissolves
grown sugar dissolves faster than a cube because grow sugar has more surface area
salt water
it dissolves with all the oxygen trapped in the bottle
