Mo7-L2a: What are Physical Properties of Matter?




         Let’s Begin                                                          SOLID
                                                                              • a def nite shape.
                                                                              • a def nitive volume.
                                                                              • particle close together.

                                                                                between particles.
        A physical property is a characteristic of matter that                • particle vibrate in all
        you can observe or measure without changing the                         direction.
        identity of the matter.

        Solids, liquids, and gases are called states of matter.               GAS
        Every solid, liquid, and gas around you is made up of                 • no def nite shape.
        moving particles that attract one another.                            • no def nitive volume.
                                                                              • particles very apart.

             Anything that takes up space and display                           between particles.
                the properties of mass and inertia.                           • particle move freely.

                                                           Mass is the amount of matter in an object.

                                                           Volume is the amount of space something takes up.
                                                           Mass and volume are size-dependent properties of
                                                           matter because their values depend on the size of a
                                                           sample.

                                                           heavier therefore has more mass.

                                                           The Earth has 9.3 times more mass than Mars.
