This document discusses several physical properties of matter including magnetism, physical state, mass, relative density, solubility in water, conduction, and insulation. It explains that materials can be classified and their behavior determined based on these measurable properties, such as whether they are attracted to magnets, can change state with temperature, will sink or float, and allow the flow of thermal or electrical energy. The properties of matter help describe how it can be identified, altered, and utilized.
Intro to physical properties of matter
- 1. Physical Properties Does it Matter?
- 2. Magnetism • Matter that contains iron, iron alloys, or nickel will be attracted to a magnet • Not all metals are attracted to a magnet
- 3. Physical State • 3 forms: liquid, solid, or gas • Can change from one form to another by the processes of melting, freezing, evaporation, and condensation • Temperature changes are involved with changes in state
- 4. Mass • Mass is the amount of matter in an object. Mass is measured with a balance. • Mass is not the same as weight. • Weight is a result of the pull of gravity on an object and is measured with a scale.
- 5. Relative Density Sinking & Floating • Weight doesn’t determine if an object will sink or float. • How much space an object takes up and how much matter the object contains determines density.
- 6. Solubility in Water • Ability of a substance to dissolve when added to water • A liquid (ie: lemon juice), a solid (ie: powdered drink mix), or a gas (ie: carbon dioxide) can be dissolved in water.
- 7. Conduction • Some materials allow thermal (heat) energy or electrical energy to flow through them easily. • Such materials are called conductors.
- 8. Insulation • Some materials do not allow thermal (heat) energy or electrical energy to flow through them easily. • Such materials are called insulators.
- 9. Does it Matter? • Matter has… …measurable physical properties • Those properties determine… …how matter is classified, changed or used
