matter Flashcards
Volume + Shape = Definite/ Fixed
attraction of particles= very strong
motion of particles= only vibrate in place
solids
Volume = Definite/ Fixed
Shape= shape of container
attraction of particles= strong
motion of particles= can slide pass each other
liquid
Volume = vol of container
Shape= shape of container
attraction of particles= none
motion of particles= fasy/ random movements
gases
two classifications of matter
pure substances and mixtures
two classifications of pure substances
elements: most basic building block
Compounds: chemical unions of elements
two parts of mixtures
homogenous: uniform in appearance ( milk )
Heterogenous: can see parts (pizza)
what is the change:
change in composition material
new substance formed
burning, oxidation, rusting, tarnishing
chemical change
what is the change:
DO NOT involve composition change
same substance
changes in state (boil, freeze)
mechanical change (tearing, cut, grind)
physical change
