Unit 2 Properties Of Matter Flashcards
Chemical property
Changes composition
Physical properties
Describes the quality or condition of matter
Extensive properties
The amount of matter present matters I.e. weight
Intensive property
No matter how much you have it will always stay the same
States of matter
Solid liquid gas (plasma)
Chemical change
Reactions, flammable, combustion, formation, rust, tarnish
Law of conservation of mass
Mass is neither created or destroyed
Phase change
When matter changes from one state to another
Physical change
A change that physically happens I.e. boil, freeze
Chemical change
A change that cannot be reversed i.e. vaporize, rot, tarnish
Homogeneous mixture
Completely uniform composition throughout the mixture all considered solutions
Solution
Homogeneous mixture
Heterogeneous mixture
Not uniform in composition
Crystallization
Separation from forming solid particles from a solution
Distillation
Separating technique from boiling
Filtration
Removing sand from water
Sublimation
Separation of gases
Element
Simplest form of matter made of atoms
Compound
Two or more elements
Law of definite proportions
Mass of one element combined with mass of another element forms a compound
Law of multiple proportions
You can use the same elements but different ratios to make different substances
