The temperature o A. will also double.
B. will become four times.
C. will remain same.
D. will decrease.
The Young’s Modulus (Y) is defined as
∆l can be written as
Where l is the original length, α is the coefficient of heat expansion (a constant for a material) and ∆T is the temperature difference.
As ∆T increases, Y decreases.
