SUMMARY
The shear modulus of metals decreases with increasing temperature due to the increased energy of atomic nuclei, which facilitates the movement of atoms. As temperature rises, atoms gain energy and move closer to the positions required for gliding, thus lowering the energy barrier needed for this process. This phenomenon is primarily related to the atomic motion rather than electron energy levels. Understanding this relationship is crucial for applications in materials science and engineering.
