25\,^{\circ}\text{C}

. The vessel has an internal volume of

200\,\text{cm}^3

at this temperature. When the system is heated to

75\,^{\circ}\text{C}

the vessel is found to be just completely filled by the liquid. If the coefficient of cubical expansion of brass is

\gamma_{\text{brass}} = 5.4\times10^{-5}\,\text{K}^{-1}

, determine the apparent coefficient of cubical expansion of the liquid.
