Yes, just not as quickly
the sugar cube will be dissolved in hot or cold water but you need to stir it
The sugar cube in the hot water will dissolve faster because there are more and higher energy collisions between the water molecules and the sugar molecules which will cause the sugar to dissolve faster.
depense on the size of the cube
yes
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.
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
solubility generally increases on heating. so sugar cube in boiling water will dissolve fastest.
hot water
