The iron atoms are gaining potential energy when melted iron solidifies without any change in temperature.

What is the atomic level?

Atom refers to the smallest constituent unit of a chemical element.

As the melted iron solidifies, the phase change is happening at a constant temperature.

Kinetic energy does not change as it is dependent on temperature, therefore, there will be no change in kinetic energy.

As the melted iron solidifies, the intermolecular forces of attraction increase between the particles and the intermolecular distance between the particles decreases. For the formation of a bond, the energy required is in the form of potential energy and hence, the potential energy increases.

Therefore, the iron atoms will gain potential energy.
