Dissolving sugar in water is a physical change. You can tell this because if you were to dissolve the sugar in water and then let the water evaporate, the sugar would still be left. All of the components that you started with are still there, even if you can't see them.The fact that there is no change in volume on dissolving sugar in what tells us that there are spaces between the particles of water
No the sugar dissolves. A solution is created.
when the cube is added the water level does increase but it goes down to the original level when the sugar dissolves
No, sugar forms a solution when mixed with water.
If you meant salt water, then it will float, because the salt level rises, therefore so does the buoyancy level. Sugar, I'm not so sure about. Google will obviously tell us though.
When sugar and water are mixed, the sugar dissolves in the water, therefore water is the solvent and sugar is the solute.
Solute
Homogeneous is mixed, like stirring sugar into a cup of tea or water. However, if you put one full teaspoon of sugar into 1/4 teaspoon of water, it would not mix completely-- the sugar would remain in a mostly granulated state. Or if you mixed sugar completely into a small amount of water and let the water evaporate, the sugar crystals would begin to fall to the bottom,e.g. separate from the mixture.
Adding matter to matter with always increase overall volume
Sugar water is not heterogeneous because you can't see the components it's made of. The particles are mixed up on an atomic level.

Sugar water
Steam.
Water with sugar mixed in.
The sugar disinigrates and is part of the water
A mixture because the sugar is mixed in the water
The water level rises
The oil will rise to the top and float on the water.
