Question

why do sound waves travel slowest in gases? a gass particles are very close together. a gass particles are magnetic. a gass particles are very far apart.

Explanation:

Sound waves need particles to transfer energy. In gases, particles are far apart. This makes it harder for energy to be passed on quickly. In solids, particles are close, so sound travels fast. In liquids, it's in - between. Option A is wrong as gas particles are not close. Option B is wrong as gas particles' magnetism is not related to sound speed. Option C is correct as far - apart particles slow sound.

Answer:

C. A gas's particles are very far apart.
