The correct ranking of the phases of matter from the one with the least kinetic energy to the greatest kinetic energy for the particles in the substance is:
Least solid ↓ liquid ↓ gas Greatest
In this ranking:
- Solid has the least kinetic energy as particles are closely packed and vibrate in place.
- Liquid has more kinetic energy than solid; particles are still close together but can move past one another.
- Gas has the greatest kinetic energy; particles are far apart and move freely and rapidly.
