This means that each atom will take up more space due to it's movement so the material will expand. When it is cold the kinetic energy decreases, so the atoms take up less space and the material contracts. Some metals expand more than others due to differences in the forces between the atoms / molecules.In metals such as iron the forces between the atoms are stronger so it is more difficult for the atoms to move around. In brass the forces are a little weaker so the atoms are free to move about more.ome metals expand more than others due to differences in the forces between the atoms / molecules.
