Thermal Expansion Coefficients Relation

The relation between coefficient of linear expansion (\(\alpha\)) and coefficient of volume expansion (\(\gamma\)) for solids is
\(\gamma = 2\alpha\)
\(3\gamma = \alpha\)
\(\gamma = 3\alpha\)
\(2\gamma = 3\alpha\)

Solution:

Coefficient of volume expansion is three times the coefficient of linear expansion for an isotropic solid, i.e., \(\gamma = 3\alpha\).
