Chemical and Physical Properties CHEMISTRY Chemical and Physical Properties

Fold your page into two columns Physical Properties chemical Properties

Properties of matter Matter has many properties and these properties are the characteristics that describe matter. Physical Properties 2. Chemical Properties

Physical properties Properties of matter that can be measured or observed without the matter changing its identity Physical Characteristics of matter The things you detect with your 5 senses (see, smell, taste, feel, sound) Color, size, density, state of matter

Physical Properties Examples Density  Mass / Volume State of Matter  Solid, Liquid, Gas Freezing & Boiling Points 5 Senses: Taste, Touch, smell, sound, Sight Ability to: Conduct/ insulate Heat Conduct/ Insulate Electricity Solubility – Dissolve in other Substance Magnetic

State of matter is a physical property Phase change diagram Sublimation Deposition

In magma, viscosity is affected by the silica content and temperature. The “thickness” of a liquid. The amount of resistance a liquid has to flowing. In magma, viscosity is affected by the silica content and temperature. Viscosity is a physical property

Rate these substances from the most viscous to the least viscous:

Malleability Malleable The ability to be hammered into a thin sheet. Usually a soft metal has this property

Ductility/Ductile Can be stretched into a thin wire

More Physical Properties Luster: shiny, usually metallic Adhesive: Sticky, like tape Magnetic: Like a magnet Moldable: can be formed into a sculpture Elastic: stretchy, like rubber Flexible/pliable: can be moved or bent without breaking Crumbly: soft, like a powder Texture: Bumpy, smooth, rough

chemical Properties Describes The ability or inability for a substance to change into one or more new substances “Potential” to change

Chemical Properties Flammabile Reactive Toxic Corrosive Explosive

Flammability: will it burn or ignite? The only way to find out is by trying it! Then, you have changed it permanently.

Reactivity – Reactivity: the ability of matter to undergo a chemical reaction and release or absorb energy either by reacting with itself or other types matter

the degree to which a substance can damage an organism Toxicity the degree to which a substance can damage an organism

Examples: Strong acids and bases are corrosives.    a substance that has the power to cause irreversible damage or destroy another substance by contact. Examples: Strong acids and bases are corrosives.

Radioactive, Radiation:A stream of particles or electromagnetic waves that is emitted by the atoms and molecules of a radioactive substance as a result of nuclear decay. Rubidium - 87 Uranium - 238 Thorium - 232 http://listverse.com/2013/02/06/10-things-you-probably-didnt-know-were-radioactive/

Rusting is Oxidation When it reacts with oxygen to permanently change it

Properties: Characteristics: traits Physical Properties Chemical Properties 5 Senses: color, luster, size, density Solid, liquid, gas Conduct/insulate heat or electricity Solubility Magnetic Viscosity Malleability Ductility Pliability Adhesive moldable Potential to change permanently Flammable Reactive Toxic Corrosive Radioactive Explosive Rusting/oxidation
