  1. Physical and Chemical Properties9/16/2014 Please get your notebook & add this title and date Warm Up: what is a “characteristic property?”

  2. Notebook Set Up 14Physical & Chemical Properties • Warm Up: what is a “characteristic property?”

  3. Characteristic Property • A characteristic property of matter refers to the properties that are commonly used to identify and describe matter. • We will review some of these terms today • Be ready to add a lot of terms to your glossary!

  4. Properties of Matter-Words to Know…

  5. Matter Anything that has mass and takes up space!

  6. Mass • A measure of how much matter is in an object.

  7. Weight • A measure of the force of gravity on an object.

  8. Volume • The amount of space that matter occupies.

  9. Density • The measurement of how much mass of a substance is contained in a given volume. • Mass/Volume • I Density

  10. States of Matter • There are different “states” of matter. No, not like Texas, Oklahoma, New Mexico. States of matter are also known as phases (a physical state of matter). • Elements and compounds can move from one phase to another phase when special physical forces are present. • Solid • Liquid • Gas • Plasma

  11. Freezing point • The temperature at which a liquid changes into a solid.

  12. Boiling point • The boiling point of an element or compound means the temperature at which the liquid form of an element or compound is at equilibrium with the gaseous form. • the boiling point of water is 100 degrees Celsius.

  13. Melting point • The temperatures at which the solid form of the element or compound 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

  14. Compound • A substance made of two or more elements chemically combined in a set ratio. • Water and salt are 2 examples of compounds.

  15. All substances have properties…Including people! Example: People can be identified by their …

  16. What are properties? • Matter has observable (qualitative) and measurable (quantitative) qualities. Add those to your glossary! • We can use general properties to identify substances. • Two basic types of properties of matter: Physical properties and Chemicalproperties:

  17. Physical Properties • Physical properties are used to identify, describe and classify matter. All the terms previously listed were physical properties. • Characteristic of a substance that can be observed (using your senses) without changingthe substance into something else.

  18. 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 alcohol • High viscosity-honey

  19. Chemical Properties • Chemical properties are characteristics involved when a substance interacts with another substance to change its chemical make-up.

  20. Alike? Different? • Draw a double bubble map in your notes to compare and contrast physical and chemical properties.

  21. Notebook Set Up 14Physical & Chemical Properties • Warm Up: what is a “characteristic property?” • Exit: • Compare and contrast physical and chemical properties. • Class Notes …. • Physical properties: Physical properties are used to identify, describe and classify matter. • Examples: • Chemical Properties: Chemical properties are characteristics involved when a substance interacts with another substance to change its chemical make-up.
