A vessel is partly filled with a liquid. Coefficients of cubical expansion of material of the vessel and liquid are gamma_v unoccupied by the liquid will necessarily

A vessel is partly filled with liquid. When the vessel is cooled to a lower temperature, the space in the vessel unoccupied by the liquid remains constant. Then the volume of the liquid (V_L) volume of the vessel (V_V) the coefficient of cubical expansion of the material of the vessel (gamma_v) and of the solid (gamma_L) are related as

At 0.^(0)C the densities of a cork and a liquid in which the cork floats are d_(1) and d_(2) respectively. The coefficient of expansion for the material of the cork and the liquid are gamma and 100gamma respectively. If the cork sinks when the temperature of the liquid is 't^(0)C' then the ratio (d_(2))/(d_(1)) is
