1. Smaller grains dissolve faster – More surface area is exposed to the solvent, increasing the dissolving rate.
2. Larger grains dissolve slower – Less surface area is available, so dissolving takes more time.
3. Crushing speeds up dissolving – Breaking a solid into smaller pieces increases surface area.
4. Liquid movement affects dissolving – Stirring helps even large grains dissolve faster by spreading the solvent around.
5. Temperature matters – Even large grains dissolve faster in hot liquids because heat increases particle
movement.
1. Why does stirring a liquid help dissolve substances faster?
How does temperature influence the rate at which substances dissolve?
Why do you think sugar dissolves faster in hot water than in cold water?
What would happen if you tried to dissolve something without stirring? Would it take longer or shorter?
