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 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 and 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 and no definite volume.
Particles spread far apart.
High energy.
Melting
Matter changing from solid to liquid. Up energy, up particle movement. Melting point=temperature substance melts at.
Freezing/Solidification
Matter changing from liquid to solid. Down energy, down particle movement. Freezing point= temperature substance freezes at.
Vaporization/Evaporation
Matter changing from liquid to gas. Up energy, up particle movement. Boiling point= temperature substance turns to gas at.
Condensation
Matter changing from gas to liquid. Down energy, down particle movement.
Sublimation
Matter changing from solid to gas. Up energy, up particle movement.
