Question

If the coefficient of areal expansion of a material is 24*10-6/degree centigrade.What is its coefficient of cubical expansion.

Answer 1

Explanation:

$\gamma = 3 \alpha \\ \beta = 2 \alpha \\ \\ \gamma = (3 \div 2) \beta \\ \\ \\ given \: that \\ \beta = 24 \times 10 {}^ - 6 \\ \gamma = 1.5 \times 24 \times 10 {}^ - 6 \\ = 36 \times 10 {}^ - 6$
