Particle Theory of Matter

Front

What is the Particle Theory of Matter?

Back

The Particle Theory of Matter states that all matter is made up of tiny particles that are in constant motion.

Front

What are the three states of matter?

Back

Solid, Liquid, Gas.

Front

What happens to particles in a solid?

Back

In a solid, particles are closely packed together and vibrate in place.

Front

What happens to particles in a liquid?

Back

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

Front

What happens to particles in a gas?

Back

In a gas, particles are far apart and move freely, filling the space available.

Front

What is diffusion?

Back

Diffusion is the process by which particles spread from an area of high concentration to an area of low concentration.

Front

What is sublimation?

Back

Sublimation is the change of state from a solid directly to a gas without passing through the liquid state.

Front

What is density?

Back

Density is the amount of mass per unit volume of an object.

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, particle movement increases, leading to faster diffusion.

Front

What is a characteristic of all particles in a pure substance?

Back

All particles in a pure substance are the same.
