Taking energy away from a substance will make its particles move
more slowly
more quickly
at the same speed
When a gas forms directly from a solid, skipping the liquid phase. it is called
deposition
sublimation
evaporation
condensation
The change from a gas to a liquid is called
condensation
evaporation
sublimation
deposition
The change in state from liquid to gas is called

In which state of matter are particles moving the slowest?
solid
liquid
gas
gummy bears
The state that matter exists in depends on its
volume
weight
temperature
mass
What is the melting point of water?
212°C
100°C
32°C
0°C
How do you make matter change state?
Add energy to it
Take energy away from it
Both of these
Both boiling and evaporation are forms of vaporization. What is the difference between them?
Boiling liquids have intense heat added to it, evaporating liquids take heat from their environment.
Boiling happens quickly, evaporation happens slowly.
Evaporation occurs only at a liquid's surface, boiling occurs throughout the liquid
All of these reasons
Adding more heat energy to particles of matter will
make them move slower
make them move faster
make them stop moving
destroy them
