BITSAT Physics Question (2024) — Solution

Question

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

Options

  1. A. changes erratically
  2. B. decreases
  3. C. increases
  4. D. remains unchanged

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.
