Will sugar cubes in hot water or powdered dissolve quicker?

The surface area of a substance affects how quickly it dissolves. The smaller the particles of a substance, the greater the surface area and the faster it will dissolve. Powdered sugar has a much smaller particle size than sugar cubes, so it has a greater surface area and will dissolve more quickly.

In addition, the temperature of the water also affects how quickly a substance dissolves. Hot water molecules move more quickly than cold water molecules, so they collide with the sugar particles more frequently and break them down more quickly. This means that sugar will dissolve more quickly in hot water than in cold water.
