Science Matter 2 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 up melting point= temperature substance melts at
Freezing/ Solidification
matter changing from liquid to solid energy, particle movement down 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 up
Condensation
matter changing from gas to liquid energy, particle movement down
Sublimation
matter changing from solid to gas energy, particle movement up
Deposition
matter changing from gas to solid energy, particle movement down
