An insulated container is partly filled with oil. The lid of thecontainer is removed, 0.123 kg of water heatedto 81.0°C is poured in, and the lid is replaced. As the waterand the oil reach equilibrium, the volume of the oil increasesby 1.40x10-5 m3. The density of theoil is 922 kg/m3, its specific heat capacityis 2070 J/(kg·C°), and its coefficient of volumeexpansion is 713x10-6 (C°)-1. Whatis the temperature when the oil and the water reachequilibrium?
