booklet 2

• Liquids and gases take the shape of their container because the particles are free to move around because there are weak forces between the particles.
• solids: particles are order close together and they only vibrate on the spot
• liquid: they are touching some of there neigbering atoms and they move fairly freely.
• gas: there particals don't touch they also can move around freely
• gas to solid: deposition
• solid to gas: sublimation
• gas to liquid: condensation
• liquid to gas: boiling or evaporation
• solid to liquid: melting
• liquid to solid: freezing or solidifiying
• the point between liquid and solid is the melting point
• the point between liquid and gas is the boiling point
• the change of states are a physical change as they are a change of apperance
• a chemical change is when a substance changings into something completely new with a new chemical formula
