solute dissolves more rapidly in hot water
No, not at all

The sugar crystals have no added colour and are 'white' crystals in appearance. Once dissolved into the water, they create a transparent sugary solution. The same is for salt crystals that create a saline solution.
In unstirred water the sugar sinks to the bottom of the container. As such as it dissolves the water at the bottom becomes denser. As such it's harder for the remaining sugar to dissolve. By stirring the water the density is spread through the container allowing it mix more evenly, until it reaches the point of saturation.
because the substance in the potassium permanganate crystals are permeable to water, so that means it will dissolve instantly while poured into water Save
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.

A saturated solution will usually dissolve more solid solutes if it is stirred or heated.
