Answer:
sound needs a material medium like solid,liquid or gas to travel and be heard because the molecules of solid,liquid and gas carry sound waves from one place to another. sound can travel through vacuum or enmpty space because vacuum has no molecules which can vibrate and carry sound waves.

Answer:
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.
