Step-by-step explanation
With rise in temperature, Young’s modulus of elasticity decreases due to the increase in atomic
vibrations which leads to decrease in atomic forces. The Young's modulus is a measure of stiffness of the material. With rise in temperature, the length of the material increases which decreases its stiffness.
