Suppose you added a spoonful of sugar to hot water and another to ice-cold water. Which type of water will cause the sugar to dissolve more quickly?

1 answer

The sugar will dissolve more quickly in hot water compared to ice-cold water. This is because the molecules in hot water are moving more rapidly due to the higher temperature, which increases the collision frequency between the water molecules and the sugar molecules. This increased motion allows the sugar to break apart and dissolve faster in hot water than in cold water, where the molecular motion is slower.
