What is $\alpha_V$? On what value of $\alpha_V$ depends? Write its unit.
(N/A) $\alpha_V$ is defined as the coefficient of volume expansion. It represents the fractional change in volume per unit change in temperature.
Mathematically,$\alpha_V = \frac{1}{V} \frac{dV}{dT}$.
$\alpha_V$ depends on the nature of the material of the substance.
Its $SI$ unit is $\text{K}^{-1}$ or $^\circ\text{C}^{-1}$.
