Question

Responses

solids, because the motion of solid particles is fast
solids, because the motion of solid particles is fast

gases, because the motion of gas particles is slow
gases, because the motion of gas particles is slow

gases, because the motion of gas particles is fast
gases, because the motion of gas particles is fast

solids, because the motion of solid particles is slow

Answer 1

The correct response is:

solids, because the motion of solid particles is slow.

In solids, particles are tightly packed and can only vibrate in place, which results in lower kinetic energy compared to gases and liquids, where particles move more freely and at higher speeds.
