Consider two thermometers `T_(1)` and `T_(2)` of equal length which can be used to measure temperature over the range `theta_(1) " to " theta_(2)`. `T_(1)` contains mercury as the thermometric liquid while `T_(2)` contains bromine. The volumes of the two liquids are the same at the temperature `theta_(1)`. The volumetric coefficients of expansion of mercury and bromine are `18 xx 10^(-5) K^(-1) " and " 108 xx 10^(-5) K^(-1)`, respectively .
