6 DensityThe measurement of how much mass of a substance is contained in a given volume.Density=Mass/Volume
7 Freezing pointThe temperature at which a liquid changes into a solid.
8 Boiling pointThe boiling point of substance means the temperature at which the liquid form of a substance is at equilibrium with the gaseous form.
9 Melting pointThe temperature at which the solid form of a substance is at equilibrium with the liquid form.Basically the range at which the solid changes its state into a liquid.The melting point of water is 0 degrees Celsius
10 CondensationThe process by which a gas becomes a liquid. This is the reverse of VaporizationExample: Clouds, Dew, Side of your drinks
11 VaporizationThe process by which a gas becomes a liquid. This is the reverse of CondensationExample: Evaporation, Boiling
12 EvaporationThe process by which a solid or a liquid (usually a liquid) changes into a gas before the boiling point.Example: Water Cycle
13 What are properties? Matter has observable and measurable qualities. We can use general properties to identify substances.Two basic types of properties of matter: Physical properties and Chemical properties:
14 Physical Properties Hardness Texture Color Odor Taste Temperature Physical properties are used to identify, describe and classify matter.Characteristic of a substance that can be observed (using your senses) without changing the substance into something else.HardnessTextureColorOdorTasteTemperature
15 More EXAMPLES - Physical Size, shape, freezing point, boiling point, melting point, magnetism, viscosity, density, luster and many more.Viscosity - The resistance of a liquid to flowing.Examples:Low viscosity-water, rubbing alcoholHigh viscosity-honey
