Thermal Properties of Matter - Calorimetry Question with Solution | TestHub

A brass rod is 69.5 cm long and an aluminum rod is 49.0 cm long when both rods are at an initial temperature of 0°C. The rods are placed in line with a gap of 1.5cm between them. The distance between the far ends of the rods is maintained at 120.0 cm throughout. The temperature is raised until the two rods are barely in contact. The coefficients of linear expansion of brass and aluminum are $2.0\times 10^{-5}{\mathrm{K}}^{-1}$ and $2.4\times 10^{-5}{\mathrm{K}}^{-1}$ respectively. In figure, the temperature (in ${}^{\circ }\mathrm{C}$ ) at which contact of the rods just occurs is x. x/585 ( to the nearest integer) is
