5.8 Describe the arrangement and motion of particles in solids, liquids and gases

Solid

• Close
• Vibrating
• Little energy
• No bumping other than vibration

Liquid

• Sort of close, with some gaps
• Some movement
• Some energy
• Particles bounce / collide with each other, creating some gaps

Gas

• Far apart
• Lots of energy
• Lots of movement
• Collisions that spread particles often
• Collisions / bumping creates space between particles
