part 2 of matter Flashcards
Physical Properties
Any characteristic that can be observed using your 5 senses without changing the substance
Chemical Properties
Any characteristic that describes how matter interacts with another substance
Biological property
The characteristic of having all 9 features of living things
physical change
Change to the physical properties of matter, substance is not changed into a new substance
Chemical Change
Change to the chemical properties of matter, substance is changed into a new substance with new properties, cannot change back
Law of Conservation of Matter/Mass
Matter cannot be created nor destroyed,
The number of atoms/mass of the reactants equals the number of atoms/mass of the products.
Phase/State of matter
solid, liquid, and gas
Changed by changing temperature or pressure
solid
Definite shape & definite volume
Particles packed together and vibrate but have fixed positions Lower energy
liquid
No definite shape but has definite volume
Particles spread apart Medium energy
gas
No definite shape & no definite volume
Particles spread far apart High energy
melting
matter changing from solid to liquid
energy, particle movement melting point= temperature substance melts at
freezing
matter changing from liquid to solid energy,particle movement freezing
point= temperature substance freezes at
vaporization
matter changing from liquid to gas
energy, particle movement Boiling point= temperature substance turns to gas at
condensation
matter changing from gas to liquid
energy, particle movement
sublimation
matter changing from solid to gas
energy, particle movement
