Problem

A 500 cm3500\,\text{cm}^3 brass vessel is completely filled with kerosene at 20∘C20^{\circ}\text{C}. The vessel and the kerosene are heated together to 70∘C70^{\circ}\text{C}. Given γr(kerosene)=7.2×10−4 K−1\gamma_{r}(\text{kerosene})=7.2\times10^{-4}\,\text{K}^{-1} and γ(brass)=5.4×10−5 K−1\gamma(\text{brass})=5.4\times10^{-5}\,\text{K}^{-1}, find the volume of kerosene that overflows.
