the atoms in the metallic lattice become more energetic and vibrate with greater amplitude

Explanation:

When the temperature is raised, the atoms in the metallic lattice become more energetic and vibrate with greater amplitude. The path of the electrons in motion is hindered by the vibrating atoms and thus the electrons flow at a slower rate. As a result, the resistance of the metal increases with an increase in temperature.
