COMEDK · Physics · 10. Mechanical Properties of Solids
The temperature of a wire is doubled. The Young's modulus of elasticity
- A Will become four times
- B Will remain the same
- C Will decrease
- D Will also double
Answer & Solution
Correct Answer
(C) Will decrease
Step-by-step Solution
Detailed explanation
Young's modulus of elasticity \(Y\) is a material property that depends primarily on the nature of the material and the temperature. When the temperature of a solid increases, the interatomic distances increase due to thermal expansion, which weakens the interatomic forces. As…
