You are So Dense! Microscopic View
It’s just a phase? Potpourri ANYTHING GOES!

Ratio of a material’s mass to volume.
• What is density?
The molecules of a dense object are situated in this
manner.
• What is a close together?
In the graph below, This substance is most dense.
• What is a Substance a?
a
b
c
This happens to density when temperature decreases.
• What is increases or gets bigger?
This happens to density when pressure increases.
• What is increases?
This happens to molecules when temperature increases.
• What is move faster and farther apart?
Which liquid below has molecules that are closest
together?
*What is Golden Syrup?
The molecules in an object do this when pressure
increases.
• What is move closer together?
Which liquid below has molecules that are farthest apart?
*What is Oil?
This happens to density when pressure decreases.
• What is decreases?
Molecules that are very far apart, take the shape of their container and move around quickly are in
this phase of matter.• What is Gas?
Molecules that are very tightly packed together and barely
move around are in this phase of matter.
• What is solid?
Molecules that are spread out, take the shape of their
container and move around slowly are in this phase of
matter.
• What is a liquid?
The process of moving directly from a solid phase to a gas phase is
known as this.• What is sublimation?
On a phase diagram, gas and liquids tend to be this temperature
(general answer).
• What is a high temperature?
Sugar dissolving in water would be an example of this type of change..
• What is a physical change?
Making and baking cookies would be an example of this
type of change.
• What is a chemical change?
The variable that a person changes in an experiment.
• What is manipulated variable?
A phase of matter in which the temperature is high and the
pressure is low.
• What is a gas?
Main reason to not smoke or light a lighter near a gas station.
• What is because it can ignite the FUMES!
A word that means “cannot be further divided”.
• What is atom?
The density of water.
• What is 1 g/ml?
A variable in an experiment that is not changed.
• What is controlled?
A substance that has a very steep slope has this type of density.
• What is a HIGH density?
A substance that has a density of .45g/mL will do this when
dropped in water.• What is FLOAT?
