Particle theory of matter
Matter is made of tiny particles (atoms)
They consistently vibrate with energy
Closer they are - stronger bonds
What are solids
Particles close together in a fixed pattern
They can only vibrate
Held together by strong forces
What are liquids?
Particles are close
They can move around but still held together
Held together by medium forces of attraction
What are gasses?
Particles are far apart
Move independently from each other
Weak forces of attraction between them
Properties of solids
Keep their shape
Keep their volume
Unable to be compressed
Properties of a solid keeping its shape?
Strong bids between the particles
Remain rigid structure
Properties of a solid keeping their volume?
Tightly packed with no space in between
The strong bonds don’t allow them to spread out
Properties of a solid unable to be compressed
Particles are tightly packed with no space in between
What are the properties of a liquid?
Takes shape of container
Keeps their volume
Unable to be compressed
Properties of gas?
Takes shape of the container- do not have bonds
Takes volume of container- no bonds so they are able to fill out the container
Compressible - able to be squashed together
Solid to liquid
Melting
Liquid to gas
Evaporation
Gas to liquid
Condensation
Liquid to solid
Freezing or solidification
Solid to glass
Sublimation
