Key Concept Flip

State *four* distinguishing properties of a solid, compared to liquids and gases, focusing on arrangement and movement of particles.

Answer Flip

- Fixed shape
- Fixed volume
- Particles tightly packed/regular arrangement
- Particles vibrate about fixed positions

Key Concept Flip

Describe the arrangement and motion of particles in a gas and explain how this differs from the arrangement and motion in a solid.

Answer Flip

- Gas particles are far apart and randomly arranged; particles move randomly at high speeds.
- Solid particles are closely packed in a regular arrangement; particles vibrate about fixed positions.
- Thus, gases are compressible/fluid, solids are not easily compressible/rigid.
