Presentation Transcript

  1. Investigation 7, Part 1 “Dissolve and Melt”

  2. Investigation 7, Part 1 “Dissolve and Melt” • Which melted? -Under what conditions? -What happened at the particle level when it melted? 2. What dissolved? -Under what conditions? -What happened at the particle level when it dissolved? • The chocolate melted when it was heated by the air. The particles began to move faster. • The candy coating dissolved in the hot water when the solid particles broke away and into the water

  3. Investigation 7, Part 1 “Dissolve and Melt” • What is the difference between dissolving and melting? • Dissolving: Solid “disappears” into a liquid • Melting: When a material changes from a solid to a liquid
