Your answer is partially correct.

An insulated container is partly filled with oil. The lid of the container is removed, $0\mathrm{.}128$ kg of water heated to $81\mathrm{.}0C$ is poured in$,$ and the lid is replaced. As the water and the oil reach equilibrium, the volume of the oil increases by $1\mathrm{.}40{10}^{-5}{m}^3.$ The density of the oil is $925k\frac{g}{m^3},$ its specific heat capacity is $1890\frac{J}{kg*C},$ and its coefficient of volume expansion is $682{10}^{-6}(C{)}^{-1}.$ What is the temperature when the oil and the water reach equilibrium?
