A brass rod and a lead rod each 80.00 cm long at \[0{}^\circ C\] are clamped together at one end with their free ends coinciding. The separation (in mm) of the free ends of the rods if the system is placed in steam bath is (coefficients of linear expansions of brass and lead are \[2\times {{10}^{-5}}/{}^\circ C\] and \[1.0\times {{10}^{-5}}/{}^\circ C\] respectively)
