CFA 1.2 Dynamic Nature of Particles Flashcard

Front

Why do changes in temperature affect the state of matter of a substance?

Back

Temperature reflects changes in particle energy, which affects their arrangement and movement.

Front

What is the main factor that determines the state of matter of a substance?

Back

The energy of its particles and how those particles are arranged and interacting.

Front

If a liquid is cooled and energy is removed, what is most likely to happen to its particles?

Back

They will vibrate less and become more organized, forming a solid.

Front

Which of the following best explains why a solid has a definite shape?

Back

Its particles possess the least amount of kinetic energy and vibrate in fixed positions.

Front

How does the kinetic energy of particles influence their arrangement and movement in a gas?

Back

Particles move randomly and rapidly, filling any available volume.

Front

Define kinetic energy in the context of particles.

Back

Kinetic energy is the energy that particles possess due to their motion.

Front

What happens to the kinetic energy of particles as temperature increases?

Back

The kinetic energy of particles increases, causing them to move more rapidly.

Front

Explain the arrangement of particles in a solid.

Back

Particles in a solid are closely packed together and vibrate in fixed positions.

Front

Describe the arrangement of particles in a liquid.

Back

Particles in a liquid are close together but can move past one another, allowing liquids to flow.

Front

What is the arrangement of particles in a gas?

Back

Particles in a gas are far apart and move freely, filling the entire volume of their container.
