P.3 Phase Change Unit Test 2024-25

Front

What happens to kinetic energy and temperature when energy is transferred out of a substance?

Back

Kinetic energy and temperature decrease.

Front

What is the process called when liquid water changes to an ice cube?

Back

Freezing (congelación).

Front

What type of energy does an object have because it is moving?

Back

Kinetic Energy.

Front

What must overcome kinetic energy to cause molecules to have less freedom of movement?

Back

Molecular attraction.

Front

Which substance has a stronger molecular attraction if its molecules are moving in place compared to another substance's molecules that are moving around each other?

Back

Substance X.

Front

Define freezing in terms of phase change.

Back

Freezing is the process where a liquid turns into a solid as it loses energy.

Front

What is the relationship between temperature and kinetic energy in a substance?

Back

As temperature decreases, kinetic energy also decreases.

Front

What is the term for the energy stored in an object due to its position?

Back

Potential Energy.

Front

What occurs during vaporization?

Back

Vaporization is the process where a liquid turns into a gas.

Front

What is condensation in the context of phase changes?

Back

Condensation is the process where a gas turns into a liquid.
