Define Matter Anything that has mass and volume
Give three examples of “not matter” light electricity and heat
The universe is made up of energy and matter .
What three categories are chemists interested in when they study matter?
Properties, Structure (the form or shape of a substance), and Composition (parts that make up a
substance)
Define Properties Features of a substance; properties describe how matter interacts with other matter.
Define Extensive properties depend on the amount of a substance
Examplesof extensive properties Mass and volume
Define Intensive properties depend on the identiy of a substance
Examplesof intensive properties Malleability, magnetization, melting point, boiling point,
freezing point condensation point, density
Name and describe the Physical Properties that are mentioned.
One can observe and measure physical properties without changing the identity
Ex: mass, color, texture, scent, volume, hardness
What does Physical Change do to a substance? Physical changes do not change the identity of a substance
Ex: changes in states of matter
Chemical changes are chemical reactions that change the identity of matter.
States of Matter
Name the three classical states of matter:
Solid
Gas
Liquid
Melting, Freezing
Vaporizing, Condensing
Use the following chart to complare the three classical states of matter.
State of Matter
Volume
Shape

Desctibe the
Arrangement of
Particles and the
Attraction between
the particles
Fixed pattern
Strong attraction
close together,
random pattern
enough attraction
to keep together
Far apart, random
motion
Very weak
attraction
Categories of Matter
Recreate the flow chart he draws in the video. Feel free to add examples, definitions, or pictures to help
you learn this material.
Matter
Pure Substance
Elements (Periodic
Table)
Compounds
(Elements chemically
combined, bonded)
Mixture
Homogeneous
Heterogeneous
Uniform throughout
the substance
When taking a
sample from a
substance, each
sample is different
Often called a
solution
Ex: Chocolate chip
cookie each cookie
(sample of the
batter) is different
