3.4 Phase Change Critical Juncture Assessment

Front

What happens to the molecules of a substance when it changes from gas to liquid?

Back

The molecules move slower and around each other.

Front

How does the attraction between molecules affect phase changes?

Back

Weaker attraction allows molecules to move away from each other, while stronger attraction keeps them moving in place.

Front

What occurs to the molecules of a solid when energy is added?

Back

The molecules move faster and may change to a liquid.

Front

What is the effect of energy transfer on the phase of a substance?

Back

Energy transfer can cause a substance to change phase, affecting the movement of its molecules.

Front

What describes the movement of molecules in a liquid?

Back

Molecules in a liquid move around each other.

Front

What describes the movement of molecules in a solid?

Back

Molecules in a solid move in place.

Front

What happens to the molecules of a gas when it cools down?

Back

The molecules slow down and may change to a liquid.

Front

What is the relationship between temperature and molecular movement?

Back

Higher temperatures increase molecular movement, while lower temperatures decrease it.

Front

What happens to a substance's molecules when energy is removed?

Back

The molecules slow down and may change to a solid.

Front

What is a phase change?

Back

A phase change is the transition of a substance from one state of matter to another, such as solid, liquid, or gas.
