What is real and apparent expansion of liquid?

The relation between real and apparent expansion of a liquid is

Find the relation between real and apparent expansion of liquid.

Define coefficients of real and apparent expansions of a liquid. Give relation between them.

The coefficients of real expansion of a liquid is gamma and the coefficient of linear expansion of the material of the containing vessel is alpha . Then the condition for no apparent expansion of the liquid in that vessel is

Real expansion of a liquid = apparent expansion of the liquid + volume expansion of the _________. [Fill in the blank]

Is the coefficient of apparent expansion of a liquid fixed?

Define the apparent thermal expansion of liquids.

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

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) .
