Which of the following would conduct sound waves fastest?
hot air (70°C)
cold air (10°C)
cold metal (10°C)
hot metal (70°C)
1 answer
Hot metal (70°C) would conduct sound waves fastest as sound travels faster through denser materials. Metals are dense materials and their particles are closely packed, which allows sound to move quickly through them. Hot metal has more energy, which means the particles have more kinetic energy and are vibrating more rapidly, making it easier for sound waves to travel through.
