Particle Model and States of Matter

What is the Particle Model?

Explains the properties of substances based on tiny particles.

What defines a solid?

Particles are closely packed with strong bonds.

How do particles behave in a gas?

They move freely with weak or no attraction.

What happens to particle movement when temperature increases?

Particles move faster with more energy.

Do solids have a fixed shape?

Yes, due to strong attractions between particles.

How do liquids differ from solids in terms of flow?

Liquids can flow as particles can move over each other.

Can gases be compressed?

Yes, due to large spaces between particles.

What is the relationship between particle energy and state of matter?

More energy means less solid and more fluidity.

Do liquids have a fixed volume?

Yes, because particles remain close together.

What happens to solids under compression?

They cannot be compressed due to no space between particles.
