3What is Matter? Matter is the “stuff” that makes up everything. Matter is anything that has mass and takes upspace (volume). Therefore matter is anythingthat has DENSITY!

8PROPERTIES OF MATTER Physical Properties Can be observed or measured without changing the chemical makeup of the substance.Examples include: Color, Density, Taste, Texture, MassChemical PropertiesCan be observed only in chemical reactions involving the substance.Examples include: Ability to rust, flammabilityCharacteristic PropertiesAre very specific to each type of matter, like fingerprints. They are UNIQUE to that substance and are used to identify matter.Examples include: density,melting, boiling and freezing points, and conductivity
9CHARACTERISITC PROPERTIES BECAUSE THEY ARE UNIQUE TO THAT SUBSTANCE PROPERTIES OF MATTERLETS REVIEW!Melting point, boiling point, and freezing point are all examples of what kind of property? Why?CHARACTERISITC PROPERTIES BECAUSE THEY ARE UNIQUE TO THAT SUBSTANCE
10Shape, volume, and mass are examples of what kind of property and why? PROPERTIES OF MATTERLETS REVIEW!Shape, volume, and mass are examples of what kind of property and why?PHYSICAL PROPERTY because it is used to describe a substance BUT it is not a characteristic property because these things are not unique to that substance.
11PROPERTIES OF MATTERLETS REVIEW!Flammability, rusting, reacting with water are examples of what kind of property?CHEMICAL PROPERTY because it is used to describe a substances ability to react with another substance.
12PHYSICAL PROPERTIESBesides density, boiling point freezing point, melting point, condensation, taste, color…. Are there any other examples of physical properties?MalleabilityHardnessDuctilityElasticityConductivitySolubility
13CHANGES IN MATTER PHYSICAL AND CHEMICAL CHANGES A physical change is when there is a change in the matter but NO NEW substances are formed.What are some examples?Usually there is a change in the SIZE, SHAPE, or STATE that the matter is in… remember… no new substances are formed/produced!HINT: Usually, physical changes are reversible
14CHANGES IN MATTERA chemical change is a change in matter where NEW substances are formed.How do you know that a new substance has formed?The properties of the matter have changes! Like …color, density, boiling pt, solubility, etc.HINT! Usually, chemical changes are NOT reversible.
15CHANGES IN MATTERLET’S REVIEW!It is sometimes difficult to tell whether a chemical or a physical change has occurred. Here are some clues that might help:Burning always indicates chemical changeIf a NEW color appears, it is a chemical changeA change in the state of the matter indicates a physical change. Do not get confused with gas production which is a chemical change.Dissolving is a physical change…it is reversible
