6. Physical Properties of Matter Melting Point Boiling Point Solubility

7. Melting Point The temperature at which a substance changes from a solid to a liquid. The melting point varies depending on the substance

8. Physical Properties of Matter Melting Point Boiling Point Solubility

9. Boiling Point 4. The temperature at which a substance changes from a liquid to a gas (evaporation). 100 o C Boiling Point of Water The boiling point varies depending on the substance

12. Physical Properties of Matter Melting Point Boiling Point Solubility

13. What is solubility? 5. Solubility = how easily a solute dissolves in the solvent to form a solution or a homogeneous mixture. Solubility is a physical property of matter

14. What is a saturated solution?

15. Saturation 6. Saturated: when a solution contains the maximum solute it can hold. Cannot fit any more (any extra solute added would sink to the bottom)

16. Processes for Properties of Matter Evaporation Condensation Sublimation

17. Exit Slip 1. What is the difference between a solute and a solvent. 2. When a solution has as much solute as it can hold we call this ________________. 3. When a solution has less solute than it can hold we call this _________________. 4. Does the size of the sample affect its melting point or boiling point? 5. Why are melting point, boiling point, and solubility physical properties?
