2 Matter is anything that takes up space and has mass
3 Law of Conservation of Matter Statement that matter can change from one form to another but can not be created or destroyed
4 PropertiesAre characteristics or descriptions that make an object unique to other objectsTwo kinds of PropertiesPhysicalCan be observed or measured without changing the identity of the matterChemicalMatter that can change into new matter with different properties
5 Physical Properties Color Luster Size Composition Elasticity Malleability
6 Physical Properties Volume Density Mass States of matter Thermal conductivitySolubility
7 1. Color and SizeRed SmallGreen MediumBlue LargeEtc.
8 2. LusterAbility to reflect lightShiny metals, glass, mirrors, etc.
9 3. Composition Refers to what an object is made of Wood Glass Plastic Cork
10 4. ElasticityRefers to how much the object will bend or stretch without breaking and return to its original shape
11 5. MalleabilityAbility of a substance to be rolled or pounded into thin sheetsEx. Aluminum foil
12 6. Volume Refers to the amount of space an object occupies Volume can be found by 2 methodsMeasuringWater displacement
13 7. Density Refers to the amount of matter in a given space or volume Density can be found by using the following formulaDensity = Mass divided by volume
14 8. Mass Refers to the amount of matter in an object Mass can be found by using a triple beam balance scale
15 9. Weight Refers to the pull of gravity on an object You can measure the weight of an object by using a spring scaleMass and weight are not the same thingEx. You will weigh less on the moon than on earth because the moons gravity is 1/6 that of the earths
17 11. Solubilityis the ability of a substance to dissolve in another substanceex. Flavored drink mix dissolves in water
18 12. Thermal ConductivityIs the rate at which a substance transfers thermal (heat) energyEx. Foam cups do not transfer thermal energy
19 Solids Have a definite size and shape Can change to a liquid if heat is added known as the melting pointParticles are packed very closely togetherParticles can not move only vibrate back and forth
20 Liquids Takes the shape of the container but has a definite volume Can be changed to a solid at 32 degrees Fahrenheit (freezing point) 0 degrees CelsiusCan be changed to a gas at 212 degrees Fahrenheit (boiling point) This is referred to as evaporation100 degrees CelsiusParticles are loosely packed togetherShake fast and move around easily.
21 Gas Does not have a definite shape or size Fills any space that is emptyParticles are very far apartParticles move freely in all directions
22 PlasmaPlasmaDoes not have a definite shape or volume and the particles have broken apart example: lightning, fire, and aurora borealis
23 Chemical Properties Reactivity with Oxygen-forms a new substance Iron rustsNonreactivity with Oxygen- does not reactChrome bumpers on cars do not rustFlammability- easily burnsPropane gas burns easily-used in stoves and ovensNonflammability- does not burn easilyAluminum or metal pots to cook in
