CHANGING MATTER
I will discover how matter changes.
My goal is ________________.
Chapter

substance- a single kind of matter
that 6is Changing
pure.
physical property- a characteristic of matter that can be observed or measured without changing the
type of matter
physical change- an event that alters the form or size of matter but does not change the type of matter
chemical bond-the force of attraction that holds atoms together within a molecule
mixture-a combination of two or more substances are evenly distributed
soluble-able to be dissolved in a given solvent
insoluble-unable to be dissolved in a given solvent
chemical change-an event which rearranges chemical bonds and forms one or more new substances with
different properties
chemical property-a characteristic that describes when or how a substance will interact with other
substances
combustibility- the ability to burn
nuclear change-an event that greatly alters the nucleus of an atom
solution-a type of mixture in which two or more substances are evenly distributed
KEY IDEAS TO STUDY
Physical changes only change the form or size of matter while the substances keep the same properties
Changing matter often involves breaking or forming various types of bonds
Chemical changes form new substances with different properties by rearranging the atoms within
molecules
Nuclear changes form different elements by changing the nucleus of the atom

Physical Change
substance- a single kind of matter that is pure and possesses specific set of properties
physical property- a characteristic of matter that can be observed or measured without changing the type of
matter
physical change- an event that alters the form or size of matter but does not change the type of matter
The building blocks of all matter are elements such as oxygen and carbon
When atoms join together they are molecules
Molecules that contain more than one type of element are known a compounds
The positive end of one molecule attracts the negative end of another molecule
When bonds are broken and the molecules are able to move around
During a physical change, the major changes is the distance between the molecules
Mixtures and Solutions
mixture-a combination of two or more substances are evenly distributed
soluble-able to be dissolved in a given solvent
insoluble-unable to be dissolved in a given solvent
Solution-a type of mixture in which two or more substances are evenly distributed
Physical Change=separation of a mixture-trail mix
Apple juice is a solution of sugar and water
Chemical Change
chemical change-an event which rearranges chemical bonds and forms one or more new substances with
different properties
chemical property-a characteristic that describes when or how a substance will interact with other substances
combustibility- the ability to burn
In a chemical change molecules are rearranged also known as a chemical reaction
Wood, gasoline, and oxygen are combustible
In a chemical change, when the substances interact with each other the substances changes completely
Nuclear Change
nuclear change-an event that greatly alters the nucleus of an atom
atoms are made of protons, neutrons, and electrons
center of an atom is the nucleus
During a nuclear change an element can gain or lose protons, neutrons, or other particles
Combustibility
During the process of combustion, the fuel reacts with oxygen giving off heat
energy
New substances during combustion are know as exhaust
