Vocabulary
Very small unit that makes up matter
Particle
We know that air has matter because it has these two things
Mass and takes up space
Anything that has mass and takes up space
Matter
This heats the air inside the hot air balloon
fire or flame or burner
The part of the hot air balloon that holds the people
Cargo Basket
State of matter with no shape or volume and particles that are very spread out
gas
When air particles are heated up, their motion does what?
Increases
Mass
This is what happens to gas in a container when we add thermal energy
Expand
This is the part that you increase or decrease to make the balloon rise or fall
flame or burner
Flow of thermal energy from matter with a high temperature to matter with a lower temperature
Heat
Air particles do this when they are heated
Expand
These three things do not have matter
Energy, light, and sound
When the air inside the envelope is cooled, the air particles do this.
Contract
This part is a lightweight cover that fills with hot or cool air
envelope
This is the amount of space that an object takes up.
Volume
Air particles do this when they are cooled
Contract

Gas
This is what happens to the volume and shape of air particles in a container.
They spread out and fill the shape and volume of the container
As this type of energy increases, the air particles increase so they move faster.
Thermal energy
