A solid whose volume does not change with temperature floats in a liquid. For two different temperatures `t_1` and `t_2` of the liqiud, fraction `f_1` and `f_2` of the volume of the solid remain submerged in the liquid. The coefficient of volume expansion of the liquid is equal to

A body with negligible volume expansivity floats in a liquid partially submerged. For two different temperature t_(1) and t_(2) of the liquid, fractions eta_(1) and eta_(2) of the volume of the solid remain submerged in the liquid. The coefficient of volume expansion of the liquid is equal to:

A solid whose volume does not change with temperature, floats in a liquid. Fractions f_(1)andf_(2) of its volume remain submerged for two different temperatures t_(1)andt_(2) of liquid. The volume coefficient of expansion of liquid is

In a vertical U -tube containing a luquid, the two arms are maintained at different temperatures, t_(1) and t_(2) . The liquid coplumns in the two arms have heights l_(1) and l_(2) respectively. The coefficient o0f volume expansion of the liquid is equal to
