3 ways to classify matter |
properties phase composition |
ppc |
|
|
quantitative property |
depends on the amount of matter in a sample |
ex: mass and volume |
|
|
qualitative property |
depends on the type of matter in a sample, not the amount |
ex: hardness and color |
|
|
quality/condition |
can be observed or measured without changing the substances composition |
|
|
|
physical change |
boil, freeze, melt, condense, break, split, grind, cut, and crush |
|
|
|
chemical property |
the ability of a substance to undergo a specific chemical change |
|
|
|
chemical change |
the composition of matter always changes |
|
|
|
reactant |
substance at start |
|
|
|
product |
substance produced in reaction |
|
|
|
clues for chemical change |
transfer of energy change in color production of gas formation or a precipitate( a soil is that forms and settled out of a liquid mixture) |
|
|
|
pure substance |
matter that has a uniform and definite composition |
ex: silver gold and aluminum |
|
|
element |
simplest form of matter |
ex: oxygen, hydrogen |
|
|
compound/molecule |
substance that contains two or more elements chemically combined in a fixed proportion |
O, C, and H are chemically combined to form sugar |
|
|
mixture |
a physical blend of two or more pure substances |
|
|
|
heterogeneous mixture |
composition is not uniform |
sand, granite |
|
|
homogeneous mixtures |
composition is uniform |
brass, stainless steel, milk |
|
