  8. Freezing, hardness, texture, color, flexibility, solid, liquid, gas, dissolves, luster, malleable, ductile

  9. Physical properties can be used to classify matter

  10. Example: Gold

  11. Chemical Properties of Matter • Chemical Property: Is a characteristic of a pure substance that describes its ability to change into different substances

  12. Flammability, Reactivity, Rusting

  13. Methane Gas: The gas can catch in fire and burn in air, when it burns, it combines with O2 in the air and forms water and carbon dioxide.

  14. To observe chemical properties, you must change it to another substance
