Coefficient of apparent expansions of a liquid in two different vessels are `a` and `b`. Then the real coefficient of expansions of liquids, if the ratio of volume expansion of vessel of `x : y`

Coefficient of volume expansion of a gas is:

The unit for volume coefficient of expansion is

the coefficient of volume expansion is

the coefficient of volume expansion is

Define coefficient of apparent and real expansion of a liquid.

The unit for the coefficient of real expansion is

The ratio of coefficients of apparent expansions of the same liquid in two different vessels is 1:2 . If alpha_(1) and alpha_(2) are the coefficient of linear expansions then coefficient of real expansion of the liquid is

The unit for the coefficient of apparent expansion is
