Question

The numerical value of coefficient of linear expansion is independent of units of
(a) length
(b) temperature
(c) area
(d) mass

• A. only (a) is correct
• B. (a) & (b) are correct
• C. (a) ,(b) & (c) are correct
• D. (a) ,(c) & (d) are correct

Answer 1

The correct option is D (a) ,(c) & (d) are correct

Since unit of coefficient of linear expansion depends only on temperature therefore, option (D) is correct.
