Two aluminum bars have the same temperature, but different mass. Which of the two bars has the most internal energy?

The internal energy of the body W is the sum of the kinetic energies of the chaotic motion of all particles and the potential energies of interaction between the particles: W = Eк + Еп. Since both bars are made of the same material (aluminum) and have the same temperature, a bar with a larger mass will have more internal energy, since: there are more particles in it and it occupies a larger volume.
