Melting Point
What is a liquid
Takes shape of container, definite volume, loose particles
the substance that is dissolved

What is a gas
no definite shape/volume
takes shape of container
spread out particles
the substance in which the solute is dissolved
solvent
Colloid which parts of liquid are spread in a gas. (silly string)

How do you know that trail mix is a mixture?
All of the items in the trail mix can easily be separated and they all keep their own individual properties.
What causes an object to change state?
Adding or removing heat.
When temperature is removed what happens to the gas particles?
When temperature is added what happens to the liquid particles?
Gas particles get closer together to form a liquid.
The liquid particles spread out to form a gas.
