Matter is classified by…
- composition
- physical properties
Pure substance
materials made of one (1) kind of particle
mixtures
combinations of 2+ pure substances / other mixtures
Solutions (mixture type)
uniform combination
Four (4) stages of matter
- solid
- liquid
- gas
- plasma
Usually determines state of matter
- substance properties
- temperature
Six (6) processes of matter changing state
- melting / freezing
- vaporization / condensation
- sublimation / deposition
melting
solid to liquid
freezing
liquid to solid
vaporization
liquid to gas
condensation
gas to liquid
sublimation
solid to gas
deposition
gas to solid
boiling
when vaporization is too fast, liquid forms bubbles
boiling point
100C / 212F
evaporation
when vaporization takes too long & occurs below boiling point
