MATTER• Objects that take up space

and have mass.• Ex:ICE,WATER,WOOD,PEOP

LE

MATTER-GAS•Matter has 3 states gas is

one.•When a solid or liquid is

heated it can turn into gas.•The particles move in no

order bumping into each other.

•Ex:CO2,Steam,Oxygen,CO,CC14

MATTER-LIQUID• Matter has 3 states liquid is one.• When a solid is heated it turns to a

liquid.When a gas is condenses it turns to a liquid.

• The particles move smoothly pass each other.

• Ex:water,ice tea,lemon juice,coke,hot chocolate.

MATTER-SOLID• Matter has 3 states solid is

one.• When a liquid freezes it

turns to solid ice.When a gas condenses then freezes

• The particles don't move around they just vibrate in place

• Ex:ice,wood,brick,laptop,table

Physical Properties

• Can be observed or measured without changing the chemical composition

• Ex:looking at ice,checking the mass of a rock,melting ice,ripping paper,and turing pages.

Chemical Properties• Is a property that you can observe

when one kind of matter is turned into a different kind of matter.

• Ex:rust on metal,cooking eggs,burning bread,making cupcakes,and baking a cake.

Physical Change• A change that affects the size,

shape,state of matter or color of a substance but does not affect its composition.

• Ex:cutting wood,ripping paper,painting wood,melting ice,and freezing water.

Chemical Change• During a chemical change,

substances are changed into different substances. In other words, the composition of the substance changes.

• Ex:rust on metal,fireworks,baking bread,roasting meat,and burning paper.

What Are Atoms?• Atoms are the basic building blocks of matter

that make up everyday objects. A desk, the air you breath.

• Atoms are made up of eletrons, neutrons,protons.The electrons are in the shells.The protons and neutrons make up the nucleus.

What Are Elements• An element is a substance that is made

entirely from one type of atom• Ex:gold is made up of gold

atoms,wood is od made from wood atoms,sliver is made up of silver atoms,metal is made up of metal atoms,and air is made up of air atoms

What Are Compounds

• A compound is made up of two or more types of elements that are chemically combined.

• Ex:water,soda,salt,sugar,andbaking powder.

Periodic Table• The periodic table is a table of the

chemical elements, showing the symbols for the elements, their full names, their atomic numbers and their mass number. It organizes them into groups and periods (columns and rows) based on their structure and properties. It is called "the periodic table" because the horizontal rows are called "periods".

What Are Substances?• A SUBSTANCE is a material that has

constant composition, regardless of its source, also said to be pure.

• This is opposed to an impure sample which would be called a MIXTURE

What Are Mixtures?• A mixture is a substance made by

combining two or more different materials in such a way that no chemical reaction occurs.

What Is A Heterogeneous Mixture?

• Is an uneven mixture of two or more substances.

• Ex:salad,salad dressing,colourful sprinkles,soup.

What Is A Homogeneous?• Is an even mixture• Ex:powder milk,powder

lemonade,powder kool-aid,ice cream,and chocolate milk.

What Are Solutions?

• A solutions A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase.

• a solute is a substance dissolved in another substance.

• A solvent (from the Latin solvō, “I loosen, untie, I solve”) is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute,

What Is A Solubility• Solubility is the property of a solid, liquid, or

gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent
