Sublimate
To change or cause change from liquid to solid
The act or process of turning a gas to a liquid

Density
The amount of dissolved substance in a solvent
The simplest unit of measurement for a chemical compound
A measure of compactness of a substance, expressed as its mass per unit volume
Concentration
The amount of dissolved substance in a given volume of solvent
A measure of compactness
To make or become smaller, narrower, shorter, etc.
Compressibility
A measure of compactness and density
To make or become smaller, narrower, shorter, etc.

Why conduct an Experiment?
To prove your hypothesis true or false
To get consistent results
To prove a theory true or false
Deposition
Breaking down of organic material
Opposite of sublimation; gas to solid
To change from solid to gas without first melting
Brownian Motion
The theory that the volume of an object affects it's density
The almost linear curves on a line graph
The theory that particles are constantly moving
How do you gain consistent & credible results from an experiment?
Repeat the experiment and find an average
Store results in a safe place
Identify and the factors in the control group, and keep them consistent
Phase of Matter
Describes the phases of density
Describes a state of matter
Describes the life cycle
What is the Independent Variable?

Changing variable based on the dependant variable
What is the Dependent Variable?
The variable that is tested in an experiment
The variable that is depended on to record data
The variable that changes based on the independent variable, and has data collected from it
Controlled Variable/s
