A rectangular piece of iron measuring 4 cm by 3 cm at 20\(^o\)C is heated until its temperature increases by 100 C. Calculate the new area of the metal. [Linear expansivity of iron is 1.2x 10\(^{-5}\) K\(^{-1}\)]

A.

12.0144 cm\(^3\)

B.

12.0346 cm\(^3\)

C.

12.0288 cm\(^3\)

D.

12.0173 cm\(^3\)

Correct answer is C

Linear expansivity (\(\alpha\)) 

= \(\frac{A_2 - A_1}{A_1\theta}\)

Original Area(A\(_1\)) = 4 x 3 = 12

New Area (A\(_2\)) = ? 

Temp. rise (\(\theta\)) = 100\(^o\)C 

A\(_2\) - 12 = 1200 x 2 x 1.2 x 10\(^{-5}\) 

A\(_2\) - 12 = 2880 x 10\(^-5\)

A\(_2\) - 12 = 0.0288

A\(_2\) = 12.0288 cm\(^2\)
