Sugar will dissolve faster in hot water than it will in cold water.
Salt will dissolve faster in hot water compared to cold water. This is because the heat in the hot water speeds up the movement of the water molecules, allowing them to interact more readily with the salt particles and dissolve them quicker.
Most chemical salts dissolve faster in hot water than in cold water.
