part a\nsound waves are compression or longitudinal waves that travel through matter. sound travels through all three mediums, solids, liquids, and gases, at different speeds. which statement best explains why sound travels fastest through solids and slowest through gases?\na it is easier for waves to pass through gases, then liquids, then solids.\nb hard surfaces of solids cause sound waves to bounce off more quickly than in gases.\nc tightly - packed molecules of solids vibrate more quickly than loosely - packed gas molecules.\nd molecules in solids are spread apart while molecules in air are grouped together in clusters.
Answer
# Brief Explanations:
Sound is a mechanical wave that requires a medium to travel. The closer the molecules in a medium are packed, the faster sound can travel as the vibrations can be transferred more quickly. Solids have tightly - packed molecules compared to gases which have loosely - packed molecules.
# Answer:
C. Tightly - packed molecules of solids vibrate more quickly than loosely - packed gas molecules.
