Matter

• Any thing that has mass and volume but it has to have both of them

• This basket ball has mass and volume

Not matter

• Any thing that doesn’t have mass and volume it can have one of those or none

light is one of the few substances that is not matter

Pure substance

• A substance only made of one substance

Water is a pure substance

Element

• A class of substances that cannot be separated into a simpler substances by using chemical means

Compounds• a pure substance made of two or more

elements whose composition is constant

This faucet has a metal plating on It so it not an element

Mixtures

two or more substances that are not combined and that exist in no fixed proportion to each other.

Gatorade is a mixture

Heterogeneous Mixtures

• You can see the different substances in the mixture

Homogenous Mixtures

–A mixture that u cant see the different parts or substances in it

Mass

• The weight of something or how much gravity pulls on the object

• This flash drive has little mass

Volume

• The amount an object can hold

» The formula for volume is length times height times width

Suspension

• A fluid where particles hang in the

air

Emulsion

• A mixture where the particles are un dissolved

• the sugar is un dissolved in the liquid

Mechanical Mixture

• a mixture that its parts can be separated by using mechanical means

• This is copper plated and can be broken down

Reversible change

• A change that can be changed back

• The water is evaporated at the top

Non reversible change

• Impossible change

• this cant be fixed even with glue cause it is a substance that glue wont stick to

Physical and Chemical change

• Changes in either by physical means or chemical means

• Examples of Chemical change are Burning a piece of paper and freezing water

• Examples of Physical change are ripping a piece of paper and breaking a pencil
