Because the particle of the sugar are heavier that the particles of the rubbing alcohol so they tend to stay at the bottom of the container and do not dissolve p.s. I an not sure about this answer but hopefully it helps
Sugar is dissolved easily in water.
Crushing the sugar cube allows more surface area with the water that hydrates (dissolves) the sugar molecules. Therefore, it will dissolve faster. Stirring helps.
solubility generally increases on heating. so sugar cube in boiling water will dissolve fastest.
Granulated sugar would dissolve faster because there is more surface area exposed to the water.
By heating the saturated sugar solution, and then adding more sugar.
the sugar cube will be dissolved in hot or cold water but you need to stir it
depense on the size of the cube
yes

no

As you are not agitating and breaking away the sugar crystals, the outer layers have to dissolve before the inner layers can, causing the sugar to take longer to dissolve.
mechanical weathering
that depends on the quantity of water and the size of the sugar cube .......if i am correct

Yes, just not as quickly
hot water
