Which of the following statements accurately demonstrates that the coefficient of area expansion, (∆A/A)/∆T, of a rectangular sheet of the solid is twice its linear expansivity, αl?

Options

  1. A[∆A/A]/∆T = 2αl
  2. B[∆A/A]/∆T = αl/2
  3. C[∆A/A]/∆T = 3αl
  4. D[∆A/A]/∆T = αl/3

Correct answer

A. [∆A/A]/∆T = 2αl

Step-by-step solution

Correct Option is : (A)
[∆A/A]/∆T = 2αl
