CFA 1.2 Dynamic Nature of Particles Flashcard

Front

What happens to the particles of a liquid when it is cooled and energy is removed?

Back

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

Front

How does 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 behavior of gas particles in terms of movement and arrangement?

Back

Gas particles move randomly and rapidly, filling any available volume.

Front

Why does a solid have a definite shape?

Back

A solid has a definite shape because its particles possess the least amount of kinetic energy and vibrate in fixed positions.

Front

What determines the state of matter of a substance?

Back

The state of matter is determined by the energy of its particles and how those particles are arranged and interacting.

Front

Define kinetic energy in the context of particles in different states of matter.

Back

Kinetic energy is the energy that particles possess due to their motion; it varies with the state of matter.

Front

What is the relationship between particle energy and temperature?

Back

As temperature increases, the energy of the particles increases, leading to changes in their movement and arrangement.

Front

Explain why gases can fill any container they are in.

Back

Gases can fill any container because their particles move freely and are not held in fixed positions.

Front

What occurs to the arrangement of particles when a substance transitions from a liquid to a solid?

Back

The particles become more organized and closely packed as they lose energy.

Front

How does the kinetic energy of particles in a solid compare to that in a gas?

Back

Particles in a solid have lower kinetic energy compared to those in a gas, resulting in less movement.
