Which state of matter has the least kinetic energy: solid, liquid or gas?

1 answer

In terms of kinetic energy:

  1. Gas has the most kinetic energy. In gases, the particles are much farther apart and move freely at high speeds, leading to higher kinetic energy.

  2. Solid has the least kinetic energy. In solids, the particles are closely packed and can only vibrate in place, which limits their motion and therefore their kinetic energy.

So, to summarize:

  • Most kinetic energy: Gas
  • Least kinetic energy: Solid
