Chemistry End of Year Revision
Solids Liquids Gases
Solids
All particles araanged regularly
Cant move
Vibrate around a point
Solids are very dense
Cannot be commpressed easily
They have a definite shape and volume
Cant flow
Gases
Particles are far apart
easily compressed
no definite volume
flow easilly
no definite shape
flow easilly
have a low density
Liquids
Random arrangment
close togethor
they can move around eachother
Liquids are fairly dense
are not easily comppressed
no definite shape
have definite volume
flow easily
Pressure Diffusion Changes of States
Pressure
Gas pressure is caused by particles hitting a surface
You can increase pressure by
Increasing the tempreture
reduce volume
Diffusion
When particles move from one place of high concentration to low contentration
Changes of state
Atoms elements periodic table
Atoms
Everything is made up of Atoms
Atoms have protons and neutrons in the nucleas and electrons in the shells
Structure
Periodic Table
Atomic structure
Elements
Something what contains one type of atom
Compounds
Molecule
2 or more atoms bonded togethor
Compounds
a substance made of atoms from different elements bonded togethor
Formulae
H2 means there is 2 hydrogen atoms
O means 1 oxygen atom
Properties of Compounds
Compounds have differnt properties to what they are made of
Iron is magnetic Sulf
but iron sulfide is grey and not magnetic

That is separating mixtures and pure and impure
Deff not a phising link
