Modeling Waves through Mediums

What medium does sound travel through slowest?

• gas
• solid
• liquid
• trees

Why is sound able to travel faster through a solid than a gas?

• Gas molecules are packed tightly.
• Sound does not travel faster through a solid than a gas.
• Solid molecules are packed tightly.
• Gas molecules move slowly.
