Question

2. If volume expansion coefficient of a solid is
7.2 x 10-5/°C, what is the value of its linear
expansion coefficient?
please solve and explain this ques in detail ​

Answer 1

$\sf \: 2.4 \times 10 {}^{ - 5} /C\degree$

Explanation:

As We know,

Coefficient of Volume expansion = 3 Coefficient of Linear expansion of Solid

$\gamma = 3 \alpha \\ \\ \sf or \: \: \alpha = \frac{ \gamma }{3} \\ \\ = \frac{7.4 \times 10 {}^{ - 5} }{3} \\ \\ = 2.4 \times {10}^{ - 5} /C\degree$
