When you are making a cup of coffee, you add sugar to sweeten it up. Describe three ways that you can increase the rate at which the sugar dissolves. For each method, provide scientific explanations.

Answer 1

1. Stir it. Solubility increases with increased kinetic energy.
2. Increase the temperature. Solubility increases as the temperature increases.
3. Grind the sugar to make smaller particles. Solubility increases as the surface are of the solute increases. Smaller particles have a larger surface area than larger particles.
