Question 25 of 118

With rise in temperature, the Young's modulus of elasticity

Show answer and solution

Answer: (B) decreases

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.
