Solid
Ice
Liquid
Gas
Increasing the temperature of a group of molecules affects their movement by causing it to
Increase
Decrease
Slow
Not cause change
Decreasing the temperature of a substance causes the molecules to
Move faster
Remain the same
Expand
Slow down
A glass of water is a pure substance because it
Only made of one compound
Only made of one element

Is a balanced mixture
If you mix multiple elements together without binding them they are considered
A compound
A mixture
An element
A chemical change
A compound can be described as
A single isolated element
Different elements floating freely
Different elements bound together
A mixture of elements
By combining a liquid and gas under pressure (like shaving cream) you have a
Solution
Homogeneous Mixture
Suspension
Colloid
Ice tea has evenly distributed particles in water, making it a
Heterogeneous Mixture
Homogeneous Mixture
Suspension
Colloid
A difference between suspensions and solutions is
Suspensions have unmixed particles, solutions don’t
Suspensions have completely mixed particles, solutions don’t
Solutions are characterized by solids only
Solutions can be separated easier than suspensions
By increasing pressure, state of matter may change because (a) will increase
Weight
Mass
Decreasing temperature causes in a substance causes particles to
Increase speed
Decrease speed
Come close together
Move to the top of the container
Changing state of matter is a ______ change because ______
Physical, it can be reversed
Chemical, it cannot be reversed
Physical, it cannot be reversed
Chemical, it can be reversed
Boiling point is a (a) change
Extensive
Chemical
Inherent
Extensive changes rely upon an object's
Amount
Boiling point
Chemical Properties
Temperature

Intensive
Extensive
Chemical
Inherent
In a chemical change, an object
Can return back to its original form
Doesn’t change identity
Changes identity
Remains the same
Signs of a chemical change include (choose all that apply)
Odor
Change of State
Producing Bubbles
Cooling Down
A way to separate two liquids that are combined is
Filtration
Cool it down
Distillation
Cooling
Distillation is achieved through
Boiling and cooling of two liquids
Creating a filter
Physically separating solids
Magnetically separating iron
Burning is a chemical change because
It cannot return to its original form
It can return to its original form
It boils its components
The molecules separate
A quick way to check for a chemical change is to
Take the temperature of an object
Smell for a detectable odor
Weigh the object
Measure the object
Evaporation and distillation are different because
Distillation collects the evaporated liquid
Evaporation occurs through cooling
Distillation involves hot water
Distillation separates solids
Magnetism is only effective if
The mixture contains sand and water
The mixture contains copper
The mixture contains iron
