Amplify Phase Change Assessment Review

Front

What is a phase change?

Back

A phase change is a transition of matter from one state (solid, liquid, gas) to another due to the addition or removal of energy.

Front

What happens to molecules during a solid phase?

Back

In a solid, molecules are closely packed together and only vibrate in place, maintaining a fixed shape.

Front

What happens to molecules during a liquid phase?

Back

In a liquid, molecules are close together but can move around each other, allowing the liquid to take the shape of its container.

Front

What happens to molecules during a gas phase?

Back

In a gas, molecules are far apart and move freely in all directions, filling the entire volume of their container.

Front

What is melting?

Back

Melting is the phase change from solid to liquid that occurs when a substance absorbs heat.

Front

What is freezing?

Back

Freezing is the phase change from liquid to solid that occurs when a substance loses heat.

Front

What is evaporation?

Back

Evaporation is the phase change from liquid to gas that occurs at the surface of a liquid when it absorbs enough energy.

Front

What is condensation?

Back

Condensation is the phase change from gas to liquid that occurs when a gas loses energy and cools down.

Front

What is sublimation?

Back

Sublimation is the phase change from solid to gas without passing through the liquid phase, often occurring under low pressure.

Front

What is deposition?

Back

Deposition is the phase change from gas to solid without passing through the liquid phase, often occurring under high pressure.
