Chemistry
Melting and Freezing
Freezing=liquid to solid
Melting is a change of state
Melt=solid to liquid
Particle model
Every substance has it own properties
Properties of a substance depends on three things
How its particles are arranged
How its particles move around
What the particles are like
The properties describe what it looks like and how it behaves.
Density of a shape is how much matter there is in a certain volume or how heavy it is for its size
In a substance all particles are the same
A substance is made of one type of material only
Many particles are mixtures
States of matter
The arrangement and movement of particles are different in each state
Liquid
Not as closely packed as in a solid
Particles are in contact
No fixed shape
The particles of a substances do not change
Gas
Easy to compress
Gas flows
Particles are widely spread
The state of a substance depends on the temperature
Solid
Arranged in a pattern
Particles don't move
Particles touch their neighbour
Three states=solid,liqid,gas
