In the left gap of a meter bridge there ...

In the left gap of a meter bridge there is a coil of copper and in the right gap there is fixed resistance . If the coil of copper is dipped in ice the balance point is obtained at 41.2 cm of the bridge wire . Next the coil is taken of form ice and placed in a container of hoy water . Now the balcnce point is shifted by a distance 8.1 cm towards right . What is the temperature of hot water ? (Tempertaure cofficient of resistance of copper =`42.5xx10^(-4@)C^(-1)` . )
