What happens in the regions of compressions in a sound wave?

• Particles are furthest apart

• Particles are at rest

• Particles disappear

• Particles are closest together

Why does sound travel faster in solids than in gases?

• Particles are more energetic

• Particles are less densely packed

• Solids are always warmer than gases

• Particles are more densely packed

Why can't sound travel through a vacuum?

• Because it's too cold

• Because there are no particles to vibrate

• Because sound waves are too weak

• Because vacuums absorb all sound
