solid

Definite shape and volume

properties of matter

Help us identify and classify matter; physical properties; chemicals properties

physical properties

the characteristics of a substance that can be observed or measured without changing the substance

extensive properties

depend on the amount of matter that is present

intensive properties

do not depend on the amount of matter present

chemical properties

a substance's ability to undergo changes that transform it into different substances

energy

absorbed or released

color

changes

gas

production (bubbling fizzing or odor change)

precipitate

a solid that separates from solution

irreversibility

not easily reversed

density

the ratio of the mass of a substance to the volume of the substance

Temperature

affects density

As temperature increases, density

decreases and volume increases

density formula

D=m/v

mass formula

M=DV

volume formula

V=M/D
