Question

why do waves move faster at higher temperatures and in a solid phase? there is more energy and the particles are farther apart. there is less energy and the particles are closer together. there is less energy and the particles are farther apart. there is more energy and the particles are closer together.

Explanation:

Higher temperatures mean more kinetic energy for particles. In solids, particles are closely - packed. This allows for faster transfer of wave energy as the particles can interact more quickly.

Answer:

There is more energy and the particles are closer together.
