7. Chapter 2Mass change in a closed system Review: The mass of dissolved salt Lab 2.1 Review: The mass of ice and water Lab 2.4 Review: The mass of copper and sulfur Lab 2.5 Review: The mass of a gas Lab 2.6

8. The Law of conservation of mass/matter The law of conservation of mass/matter states that the mass of a system of substances is constant, regardless of the processes acting inside the system. An equivalent statement is that matter changes form, but cannot be created or destroyed.

9. Characteristics properties of a substance: Density, Melting/Freezing point, Boiling point Examples of characteristics of an object: Color, Volume, Mass, Texture Density of a Solid = Mass/Volume (g/cm3) Density of a Liquid = Mass/Volume (g/cm3) Density of a Gas = Mass/Volume (g/cm3) Chapter 3Characteristics Properties

10. Melting is the process of heating a solid substance to a point (called melting point) where it turns liquid. An object, which has melted, is molten. Freezing is the opposite of melting; it is the process of turning a liquid to a solid. Freezing point is the same temperature as the melting point.. Chapter 3Characteristics Properties

11. Boiling Point is when the temperature plateau’s (temperature remains the same over a period of time) Examples Tops plateau’s at 83oC and BHT plateau’s at 70 oC, Isopropanol plateau’s at 85oC The greater the volume the greater the time required to find the substance boiling point, however the boiling point remains the same. Ratio is double the volume double the time. Chapter 3Characteristics Properties
