Matter:
Matter:Its what the worlds made of.
1Here are some notesThe scientific name given to all materials
is called matterMatter is anything which occupies space and has
mass.
Solids, liquids and gases occupy space and have mass, so solids,
liquids and gases are states of matter.What do you know about
matter?Solids
Liquids
Gasses
SolidsSolids hold their own shape.Cannot FlowCannot be
compressed.

given.Can flowCan be compressed

(b)(a)Set up the apparatus as shown in figure (a).Record the
mass of the empty balloon.Blow up the balloon just like in figure
(b).Record the mass of the inflated balloon.
Make sure the balance is set to grams!! STATES of matter?What
would it take for matter to move from one state to another?
Energy determines the state!
Particles in Solids:Are packed tightly together
Have very little energy
Held in fixed position by bonds
Particles in Liquids:Are loosely packed
Have medium energy levels
Particles in Gasses:Move freely
Have LOTS of energy
Mixtures may be in different phasesSolid?Liquid?Gas?
Add or Subtract Energy. . .When energy is added, particles move
faster!
When energy is taken away, particles move slower!
Solid + Energy = ?When energy is added to solids, they become
liquids!
Melting
Liquid + Energy = ?
When energy is added to liquids, they become gasses!
Boiling
Changing StatesThere are several names for matter changing
states:
