Kinetic energy best describes the motion of the particles in a piece of steel.
The helium atoms move quickly in all directions. This is cap
In solid iron, the motion of iron atoms is characterized by vibrational movement around fixed positions within a crystalline lattice structure. These atoms oscillate due to thermal energy, but they do not have the freedom to move past one another, resulting in a rigid structure. As temperature increases, the amplitude of these vibrations increases, allowing for greater atomic movement while still maintaining the overall solid form.
atoms and molecules are always moving
They have the same number of protons
Atoms in one compound switch places with atoms in another compound.

a sweeping motion
The particles in a solid are arranged in a tightly packed, orderly structure. They vibrate in fixed positions around a mean position due to their attraction to each other. The model that best describes this behavior is the "rigid lattice" model.
