"Coefficient of apparent expansion of a liquid is not constant"---why?

The coefficient of volume expansion of a liquid is

Is the coefficient of apparent expansion of a liquid fixed?

The coefficient of apparent expansion of a liquid in a brass vessel is 14.6 times 10^(-5@)C^(-1) . What will be the coefficient of apparent expansion of that liquid when it is in iron vessel? alpha for brass =18 times 10^(-6@)C^(-1) " and " alpha for iron =12 times 10^(-6@)C^(-1) .

The coefficient of linear expansion of a solid is-

Define the apparent thermal expansion of liquids.

The coefficient of apparent expansion of a liquid for two different vessels A and B are gamma_(1) " and " gamma_(2) respectively. If the coefficient of linear expansion of the material of the vessel A is alpha , then the coefficient of linear expansion of the material of the vessel B will be

Using two different containers A and B, the coefficients of apparent expansion of a liquid are found to be gamma_(1) " and " gamma_(2) respectively. If the coefficient of linear expansion of the material A is alpha , find that of the material B.
