### The properties of matter

1. 1. Chapter 2Chapter 2 The Properties of MatterThe Properties of Matter
2. 2. VocabularyVocabulary  Matter-anything that has mass and volumeMatter-anything that has mass and volume  Volume-the amount of space an object takes upVolume-the amount of space an object takes up  Meniscus-the curve at a liquid’s surfaceMeniscus-the curve at a liquid’s surface  Mass-the amount of matter in a given spaceMass-the amount of matter in a given space  Gravity-the force of attraction between objectsGravity-the force of attraction between objects due to their massesdue to their masses
3. 3. Vocabulary continuedVocabulary continued  Weight-the measure of the gravitational force on anWeight-the measure of the gravitational force on an objectobject  Newton-SI unit of force (N)Newton-SI unit of force (N)  Physical Property-can be measured or observed withoutPhysical Property-can be measured or observed without changing the identity of the materialchanging the identity of the material  Density-the amount of matter in a given volumeDensity-the amount of matter in a given volume D=m/VD=m/V  Chemical Properties-describe a substance based on itsChemical Properties-describe a substance based on its ability to change into a new substance with differentability to change into a new substance with different propertiesproperties
4. 4. More VocabularyMore Vocabulary  Physical Change- a physical change that effectsPhysical Change- a physical change that effects one or more of the physical propertiesone or more of the physical properties  Chemical Change-occurs when one or moreChemical Change-occurs when one or more substances are changed into entirely newsubstances are changed into entirely new substancessubstances

Physical ChangesPhysical Changes  Changing the sizeChanging the size  Changing the shapeChanging the shape  Dissolving in waterDissolving in water  Freezing, MeltingFreezing, Melting  Not all physical changes can be undone, but theyNot all physical changes can be undone, but they do not change the identity of the substancedo not change the identity of the substance
