Melting is change of state shows the motion of the oranges most closely model.
Explanation:
Change in the state depicted in the melting is similar to that of motion of the oranges. In this process the particle changes the state from solid to liquid. when the molecules of the solid speed abundant that the motion kills the attraction by which the molecules can now move past each other as a liquid, melting occurs. As the energy inside the solid goes up due to some external pressure or temperature, which leads to the increase of substance temperature to the melting point.
