Front

Describe the arrangement of particles in a solid.

Back

In a solid, particles are closely packed together in a fixed arrangement.

Front

Describe the arrangement of particles in a liquid.

Back

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

Front
