Properties Of Matter Flashcards
(17 cards)
How can properties be used to describe matter be classified
Matter can be classified by the two properties, intensive property, and extensive property
Why do all samples of a substance have the same intensive properties?
Every sample of a given substance has identical intensive properties because every sample has the same composition
What are the three states of matter
Solid, liquid, and gas
Ex: ice, water, and steam
How can physical changes be classified?
By reversible, and irreversible
Intensive property
Depends on the type of matter in a sample, not the amount of matter
Examples of intensive property
Color, melting point, density, and hardness/ductility-the ability of a material to resist deformation
Extensive property
Depends on the amount if matter
Examples of extensive property
Mass and volume
Mass
Measure of the amount of matter the object contains
Volume
Measure of the space occupied by the object
Physical property
Quality or condition of a substance that can be observed or measured without changing the substance’s composition
Physical properties of a substance include
Color, odor, melting point, boiling point, freezing point, malleability(metals pressed into shape), and hardness
Substance
Matter that has a uniform and definite composition
Ex:Table salt(NaCl)
Pure substance
Substances in which every sample has identical intensive properties
Ex: Gold(Au)
Physical changes
During a physical change, some properties of a material change, but the composition of the material does not change
Reversible physical changes
Involve a change from one state of matter to another
Ex:boiling, freezing, condensing, melting
Irreversible physical change
Changes that cannot be reversed
Ex: break, grind, and cut
