Dissolving Matter Answers

1. Particle size, stirring, and temperature affect dissolving time.
2. You can break or crush matter to change the particle size.
3. Smaller particles dissolve faster because more surface area is exposed to the liquid.
4. Stirring makes the particles crash into each other It also moves the particles so more solid particles are exposed to the liquid.
5. Hot water dissolves sugar faster.
6. The particles in hot water move more rapidly. They mix the matter while they move around the liquid.
7. Ben should use regular salt because smaller particles dissolve faster.
8. Ben should add sugar before he puts the tea in the fridge because sugar dissolves faster in hot water.
9. Ben can stir the coffee to dissolve the cram and sugar.
