Because molecules move quicker at higher temperature, causing them to collides more. Since they collides more, reaction occurs to be a lot faster to. And that's why things dissolve quicker in hot water than in room temperature water.
Best Answer: Generally, the hotter the water, the more of a solute will dissolve. But dissolved gases prefer cold water; when you heat water, dissolved gases will appear as bubbles long before the water boils. But the question is about salts, so let's say they get less soluble as the temperature decreases.est Answer: Generally, the hotter the water, the more of a solute will dissolve.
