Physics Question on Elasticity
With rise in temperature, the Young's modulus of elasticity
A
changes erratically
B
remains unchanged
C
increases
D
decreases
Answer
decreases
Explanation
Solution
With the rise in temperature, the Young’s modulus of elasticity generally decreases. This is because materials tend to expand and become less stiff when heated, leading to a decrease in the material’s elasticity. Therefore, the correct answer is Option 4: decreases.
