Lesson 7: Just A Phase
Key Terms
SolidA solid has definite volume and
definite shape.
The particles in a solid are closely packed and vibrate in relation to one
another.
Liquid
A liquid has definite volume, but no definite shape. A liquid takes on the
shape of its container.
GasA gas has no definite shape or
volume. Its particles have enough energy to fill the entire container it
is in.
The Phases of Matter
MeltingChanging from a Solid to a
Liquid
Freezing
Changing from a liquid to a solid
Boiling
Changing from a liquid to a gas at a substance’s boiling point.
Also called vaporization
EvaporatingChanging from a liquid to a gas at the
surface of a liquid.
Condensing
Changing from a gas to a liquid
Due to a change in temperature
Latent Heat of Fusion
The heat absorbed when a solid turns into a liquid
Latent Heat of Vaporization
The heat absorbed when a liquid turns into a gas.
