3. Sugar Dust Explosion

4. Hyper, Hypo, Iso (Tonic)* Hyper(tonic) = higher concentration of solute compared to surroundings Cells will shrink Hypo(tonic) = lower concentration of solute compared to surroundings Cell will swell Iso(tonic) = equal concentration of solute compared to surroundings Cells won’t change
