Matter P2 Flashcards
Physical Properties
Any characteristic that you can observe 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 and no definite volume.
Particles spread far apart.
High Energy
Melting
Matter changing from solid to liquid
More energy and more particle movement
Melting point = temperature substance melts at
Freezing Solidification
Matter changing from liquid to solid.
Less energy and less particle movement
Freezing Point = Temperature substance freeze at.
Vaporization / Evaporation
Matter changing from liquid to gas
More energy and more particle movement
Boiling point=temperature substance turns to gas at
Condensation
Matter changing from gas to liquid
Less energy and less particle movement
Sublimation
Matter changing from solid to gas
More energy and more particle movement
