Unit 2 - Matter and Change Flashcards
Anything that has mass and takes up space, can be a mixture
Matter
Properties used to describe matter
extensive or intensive properties
measure of the amount of matter the object contains
mass
measure of the space occupied by the object
volume
property that depends on the amount of matter in a sample
Extensive Property
examples of extensive properties
mass, volume,
property that depends on the type of matter in a sample, not the amount of matter
intensive property
examples of intensive property
Density, malleability, conductivity, absorbency
Matter that has a uniform and definite composition
substance
examples of physical property
Hardness, color, conductivity, malleability, shape, physical state, boiling and freezing
points, density,
a quality or condition of
a substance that can be observed or measured
without changing the substance’s composition
physical property
physical change
a change in the state, change in the physical shape, no change in the identity and composition of the substance
three physical states
solid, liquid, gas
A physical blend of two or more components, have variable composition
mixture
The process of separating a solid from a liquid in a heterogeneous mixture
Filtration
To pour off
Decant
A liquid is boiled to produce a vapor that is then condensed into a liquid
Distill
Not uniform throughout, identifiable, you can see what is in it, has multiple phases
Heterogenous mixture
Uniform throughout, not identifiable, can not tell it is a mixture, you can not see what is in it
Homogenous mixture
Another name for homogeneous mixture
solution
the ability of a substance to change into a new substance.
chemical properties
a new composition, new chemical and physical properties.
chemical change
a form of matter that has a definite shape and volume
solid
characteristics of a solid
The particles in a solid are packed tightly together, Potential energy dominates, Strong attractive forces
one type of atom (single or
diatomic)
element
2 or more types of atoms
bonded together
Compounds
combination of elements and/or compounds
mixture
elements that exist as pairs in nature
diatomic elements
