In the case of a metal wire, at a higher temperature there is violent thermal motion of atoms and can slightly weaken the forces and hence will strain more easily. Thus, when strain increases the value of Youngs modulus decreases. The Young's modulus of the material of a wire decreases with increase in temperature.
