What is melting?
The change from liquid to solid.
What is freezing?
The change from a gas to a liquid.
What is condensation?

gas.
What is sublimation?
This is the change from a liquid into a
gas.
What is evaporation?
In a solid, this is how the particles
move.
What is vibrate?
This has no definite shape and no definite volume.
What is a gas?
Oxygen is a gas at room temperature.
This is how its particles move.
What is fast?
These two changes in state require adding energy.
What are melting and evaporation
(and sublimation)?
These two changes in state require
removing energy.
What are freezing and condensation?
The ability to be made into thin
sheets.
What is malleability?

The explosion of fireworks is an example of this type of change.
What is a chemical change?
The release of this when you put alka
seltzer in water demonstrates a
chemical change.
What is carbon dioxide (bubbles)?
This is how properties of matter
help scientists.
What is in identification?
This is why dry ice doesn’t get food
wet.
What is sublimation?
These are two chemical
properties of matter.
What are flammability and
reactivity?
When milk or eggs go bad, this kind of
change happens.
What is a chemical change?
Oxygen, helium, propane, and
hydrogen are all usually in this
phase.
What is gas?
Volume, density and solubility are
these kinds of properties.
