|
Matter
|
Anything that has mass and occupies space
|
|
|
Properties
|
the identifying characteristics used to distinguish types of matter
|
|
|
The three states of matter
|
Solid- Liquid- Gas
|
|
|
Phase Changes
|
Solid to liquid= Melting
Liquids to Solids= Freezing Solids to gases= Sublimation Liquids to Gases= evaportation Gases to Liquids= Condensation |
|
|
The Two types of properties for matter
|
The two types are Physical which is appearance and the chemical properties which is the behavior of the chemical
|
|
|
Physical Properties of Matter
|
Characteristics of a substances that describe their appearence, state or reaction to contact
|
|
|
Melting point
|
Temperature at which a solid turns to a liquid A.K.A freezing point.
|
|
|
Boiling point
|
Temperature at which liquid turns into gas
|
|
|
Hardness
|
Resistance to scratching
|
|
|
Malleability
|
ability to pound into a flat sheet
IE aluminium |
|
|
Ductility

Ability to be pulled into wire.
|
|
|
Crystal Shape
|
The geometric shape of the pure solid.
|
|
|
Solubility
|
The ability to dissolve into a liquid
|
|
|
Density
|
the mass per volume of the substance
|
|
|
Conductivity
|
The ability to pass an electric current.
|
|
|
Chemical Properties of Matter
|
The characteristics of how a substance reacts
|
|
|
Pure Substance
|
A chemical or matter that always has the same properties because it is made up of only 1 type of matter. A pure substance can be either an element or a compound
|
|
|
Element
|
Form of matter that has only 1 type of particle in it. It is the basic building blocks for compounds. Each element has its own characteristics. All elements found on Earth are organized into the periodic table.
|
|
|
Compound
|
Form of matter that has particles made up of 2 or more elements. Examples are : water h20 and Carbon dioxide co2.
Each compound has it own properties and chemistry. |
|
|
Mixture
|
Two or more substances are combined and the resultant matter has variablle changing properties.
The substance mixed do not react chemically. The substance remain in their original form, even though they are difficult to see when combined a mixture can be homogeneous or heterogeneous |
|
|
Mechanical Mixtures
|
A mixture with differant substances visible. You can see two or more part. It can be seprated into parts physically. This is also know as a heterogeneous mixtures.
|
|
|
Solutions
|
Mixtures that appear to be the same throughout. You can only see one part. One substance is dissolved in another. Also known as a homogeneous mixture. The substance in the greater quanity is called the solvent. THe substance with less quanity is called the solute. Any substance that can be dissolved in water is called an aques solution.
|
|
|
Suspensions
|
Cloudy mixtures in which tiny particles of one substance are held with in anothe. They can be seperated. The particles can be removed through a filter.
|
|
|
Colloid
|
Cloudy mixture in which tiny particles cannot be seperated. The particles cannot be seperated easily.
|
