The table shows the speed of sound waves in various media. This table can be used as evidence for which of the following statements?

• Reasoning: Sound travels fastest through a gas.
• Claim: Water is the best substance to transfer all sound waves. Reasoning: Water has a very high specific heat and will transfer sound faster.
• Claim: Steel is more dense than copper. Reasoning: Sound can travel faster through steel because the particles are closer together allowing the energy to be transferred faster.
• Claim: Lead will transfer sound the fastest because it has a high specific heat. Reasoning: Specific heat is the best indicator of how fast a sound wave will travel.
