mass
The quantity of a three-dimensional space occupied by a liquid, solid, or gas
volume
A property of matter that changes as the amount of matter changes Ex, mass and volume
Extensive property
Properties that don’t depend on the amount of matter such as density and color
Intensive property
is observed with the senses and can be determined without destroying the object
Physical property
A state of matter characterized by particles arranged such that their shape and volume are relatively stable
solid
state of matter where particles are free to flow has a definite volume but not a definite shape
liquid
A state of matter that is characterized by molecules that are in constant motion
Gas
A substance in the gas phase at a temperature lower than its critical temperature; can be condensed o a liquid by increasing pressure without reducing the temperature.
vapor
Any change that occurs without altering the chemical composition of the substance
Physical Change
a combination of two or more pure substances in which each pure substance maintains its individual chemical properties
Mixture
composed of different constituents or dissimilar components
Heterogeneous
has the same uniform appearance and composition throughout
Homogeneous
a homogeneous mixture composed of two or more substances
solution
a physically distinctive form of matter, such as, solid, liquid, gas or plasma. A phase of matter is characterized by having relatively uniform chemical and physical properties
Phase

Distillation
Substances that can not be split into simpler substances
Elements
Chemicals made from atoms of different elements joined by chemical bonds
Compound
a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting, in the formation of at least one new substance.
