Evaluate the following statements. (A) The dimension of the...

The coefficient of linear expansion $\alpha$ is given by $\alpha = \dfrac{\Delta L}{L_0 \Delta T}$.

The dimension of $\alpha$ is $\dfrac{[L]}{[L][K]} = [K^{-1}]$.

Thus, statement A is correct.

The coefficient of volume expansion $\gamma$ is given by $\gamma = \dfrac{\Delta V}{V_0 \Delta T}$.

The dimension of $\gamma$ is $\dfrac{[L^3]}{[L^3][K]} = [K^{-1}]$.

Thus, statement B is also correct.

Both statements A and B are correct.
