Mo5-L1c: Matter: How to Identify a Substance?




                                                                                   SUMMARY
               Flammability and the ability to                            What are the Properties of Matter?
               rust are both chemical
               properties.                                         Physical properties and chemical properties
                                                                       are used to describe types of matter.
               Flammability is the ability
               of a type of matter                                Height
               to burn easily.






                Rust is a substance
                that forms when iron
                reacts with water and
                oxygen                                            Width

                1. How are properties use to identify a substance?
                                                                  Physical Properties

                            Vocabulary A-Z                        unknown substances.

                            Let us learn some vocabulary          When you identify matter using physical properties,
                                                                  consider how the properties are alike and how they

                a characteristic of matter that you can observe or
                measure without changing the identity of the matter
