Matter Part 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 Physical properties of matter,substance is not changed into a new substance
Chemical Change
Change to chemical properties of matter,substance is changed 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 but has definite volume
Particles spread apart
Medium 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
