Amplify Phase Change Review

Front

What is the main topic of the Amplify Phase Change Review?

Back

The main topic is the study of how substances change from one phase to another, focusing on the movement of molecules and energy changes.

Front

What does it mean for molecules to have 'freedom of movement'?

Back

Freedom of movement refers to how molecules can move relative to each other in different phases of matter, such as solids, liquids, and gases.

Front

What happens to the temperature and speed of molecules when kinetic energy increases?

Back

Both temperature and speed of the molecules increase.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object has because it is moving.

Front

How do molecules behave in a liquid phase?

Back

In a liquid phase, molecules move around each other but are still close together.

Front

How do molecules behave in a gas phase?

Back

In a gas phase, molecules move freely and are far apart from each other.

Front

What occurs when a liquid changes to a gas?

Back

The molecules move around each other and then move away from each other.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, kinetic energy also increases.

Front

What is the phase change from solid to liquid called?

Back

Melting.

Front

What is the phase change from liquid to solid called?

Back

Freezing.
