What is Matter?
Matter is… Everything we see around us: GlassMetal Plastic BonesBreath
Matter can be sorted into three groups: Solid - Like a brick Liquid - Like water gas- Like air
A solid doesnt take the shape of a flask So when you put a ball into a flask it doesnt fill it up or take the shape of the flask - it just stays as a ball in the flask
However a liquid does take the shape of a flask but doesnt fill it up So if we put the same liquid into different containers the liquid changes to be the same shape as the inside of the container but it doesnt fill it right up
A gas takes the shape of a flask and fills it up completely The same is true for air in a room – air will expand to completely fill a room, so we can breath everywhere. If it didnt we would only be able to breath in certain places in the room where there was air, and we would have to hold our breath in other parts where there wasnt any air.
If we heat most solids we can turn them into liquids For example if we heat a beaker of ice (solid) it turns into a beaker of water (liquid)
If we heat most liquids we can turn them into gasses For example boiling Water turns into Steam
Also, if we cool most liquids they become solids For example if its cold enough rain will turn into snow
And if we cool most gasses they become liquids Power stations release hot steam which is cooled by cooling towers and forms rain clouds which return the water back to earth when it rains
