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/ Solidification
matter changing from liquid to solid ⬇ energy, ⬇ particle movement freezing point= temperature substance freezes at
Vaporization/Evaporation
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
Deposition
matter changing from gas to solid ⬇ energy, ⬇ particle movement
