αV is a characteristic of the substance but is not strictly a constant. It depends in general on temperature as shown in figure (c). It is seen that αV becomes constant only at a higher temperature.

Q. Coefficient of volumetric expansion $α_{V}$ is not a constant. It depends on temperature. Variation of $α_{V}$ with temperature $T$ for metals is

$α_{V}$ is a characteristic of the substance but is not strictly a constant. It depends in general on temperature as shown in figure (c). It is seen that $α_{V}$ becomes constant only at a higher temperature.

Q. Coefficient of volumetric expansion αV​ is not a constant. It depends on temperature. Variation of αV​ with temperature T for metals is

αV​ is a characteristic of the substance but is not strictly a constant. It depends in general on temperature as shown in figure (c). It is seen that αV​ becomes constant only at a higher temperature.
