Vedclass · Answer

(B) The Young's modulus $(Y)$ is defined as the ratio of stress to strain,$Y = \frac{	ext{Stress}}{	ext{Strain}}$.When the temperature of a solid increases,the interatomic bonds weaken,leading to an increase in the strain for a given stress.Since the strain in the denominator increases with temperature,the value of the Young's modulus $(Y)$ decreases.Conversely,when the temperature decreases,the interatomic bonds become stronger,causing the strain to decrease,which results in an increase in the Young's modulus $(Y)$.
