3. Place the states of matter in order of increasing energy and define the type of
energy in question.
Solid, Liquid, Gas Kinetic energy
4. What is the difference between a physical and chemical change?
A physical change down not change the chemical makeup of
a substance while a chemical change does, creating something new
5. What makes a pure substance pure?
Being made of only one substance. Items on the periodic table
or even indivual compounds such as CO2 are pure
6. Use at least six shapes, (each shape represents an atom and connecting two
shapes with a ‘--‘ indicate a bond between them), to indicate the following:
a. A mixture of two compounds and one element
b. A mixture of molecules with at least one compound and one element
c. A pure substance made only of compounds
See Kasner for confirmation of your examples
7. Identify each as either an element or compound:
a. H2O
Compound
b. Al
Element
c. H2
Element
d. CO
Compound
8. Identify the two types of movement and identify how each state of matter
moves.
Intermolecular movement – movement between multiple molecules
Intramolecular movement – movement within a single molecule
Solid
Liquid
Gas
No Inter
Some inter
Fast inter
Has intra
has intra
has intra
9. List the difference between an element and a compound
Elements are made of one type of atom or element while
compounds contain different atoms or elements
10. Define the two types of mixtures.
Homogeneous mixture is the same throughout or mixed evenly
Heterogeneous mixtures have different compositions or mixed unevenly
11. Identify each of the following as either a physical or chemical change.
a. Fog on a windshield
Physical
b. Cutting up vegetables for dinner
Physical
c. A necklace leaving bluish green stains on your neck
Chemical
d. A compost heap breaking down
Chemical
12. List the difference between a molecule and an atom.
A molecule is made of multiple atoms
13. What state of matter takes up the most volume and why?
A gas, because is has the most space between molecules and
they move faster than molecules in other phases
