conversation of mass 
matter cannot be created or destroyed
density 
mass/volume
density(ρ) 
mass(m)/volume(V)
density(kg/m3) 
mass(kg)/volume(m3)
Measure length, height and width with a ruler and multiply to get volume 
How to find volume of regular object?
Place object in a displacement can
See how much water flows into measuring cylinder
That's the volume of the object 
How to find the volume of an irregular object?
gas to liquid 
condensation
liquid to gas 
evaporation, boiling, vaporization
liquid to solid 
freezing
solid to liquid 
melting
gas to solid 
deposition
solid to gas 
sublimation
physical change 
change of state
same 
mass always stays the...
kinetic energy increases 
as temperature increases
change state 
if kinetic energy stores increase/decrease enough
increases internal energy 
heating
internal energy 
sum of the kinetic and potential energies of all particles in the system
kinetic energy 
movement of particles
potential energy 
bonds breaking in the particles
state change
a change of state occurs if the substance is heated enough and the particles have enough energy in their kinetic energy stores to break the intermolecular bonds holding together
gas arrangement 
far apart, random arrangement, small amount of attraction force
when temperature rises 
kinetic energy increases
gas movement 
moving at random speeds in random directions
when changing state 
potential energy increases
gas properties 
low density
no fixed volume or shape
can be compressed
can flow
fill all available space
liquid arrangement 
particles in contact with each other
randomly arranged
some force of attraction
liquid movement 
move randomly around eachother
liquid properties 
take the shape of container
cannot be compressed
molecules move randomly, able to flow
fixed volume
solid arrangement 
tightly packed
strong forces of attraction
solid movement 
vibrate in a fixed position
solid properties 
fixed volume
fixed shape
high density
