Particle Theory and Change in State

Front

What does the particle theory state about forces of attraction between particles of matter?

Back

There are forces of attraction between the particles of matter that decrease with increased space.

Front

How does the particle theory describe the space between particles of matter?

Back

There is space between the particles of matter, and the amount of space depends on the state.

Front

What effect does an increase in temperature have on the movement of particles according to the particle theory?

Back

An increase in temperature results in an increase in the movement of particles.

Front

What does the particle theory state about the motion of particles of matter?

Back

The particles of matter are in constant motion.

Front

According to the particle theory, what can be said about the particles of a substance?

Back

The particles of a substance are identical.

Front

What is the main idea of the particle theory?

Back

The particle theory explains that matter is made up of tiny particles that are in constant motion and interact with each other.

Front

How does the state of matter affect the arrangement of particles?

Back

In solids, particles are closely packed; in liquids, they are less tightly packed; in gases, they are far apart.

Front

What happens to the space between particles when a substance changes from solid to liquid?

Back

The space between particles increases as the substance absorbs heat and the particles move more freely.

Front

What is the relationship between temperature and particle movement?

Back

Higher temperatures increase the kinetic energy of particles, leading to faster movement.

Front

What happens to the forces of attraction between particles as they move further apart?

Back

The forces of attraction decrease as the distance between particles increases.
