Classifying Matter
All matter is made up of small particles called
Atoms
liquid -> gas without reaching boiling point
evaporation
the three states of matter
solid, liquid, gas
anything that has mass and volume
matter
two or more substances that are psychically combined
mixture
Matter that is made up of only one kind of atom
element
solid -> liquid
melting
has no definite volume or definite shape
gas
the amount of material in a substance
mass
a mixture in which all the substances are spread evenly throughout
solution
When atoms of different elements combine, the molecule that is formed is called a
compound
liquid -> solid
freezing
has definite volume, but not definite shape
liquid
the amount of space an object or substance takes up
volume
a substance that is dissolved
solute
A change in matter that does NOT form a new substance
physical change
gas -> liquid
condensation
definite volume and definite shape
solid
the amount of matter in a certain volume
(HINT: where do you go to get your ID?)
density
a substance that dissolves another substance
solvent
a characteristic of a substance that can be observed without changing the identity of the substance is called a
physical property
liquid -> gas
vaporization
this is created in a chemical change but not a physical change
a new substance
technique used to find the volume of irregular solids
water displacement
the amount of solute that is dissolved in the solvent
concentration
