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

Options

  1. Achanges erratically
  2. Bdecreases
  3. Cincreases
  4. Dremains unchanged

Correct answer

B. decreases

Step-by-step solution

Young's modulus, Y = Stress Strain If the temperature increases, strain also increases. Hence young's modulus decreases.
