(B) The total thermo-emf generated between two temperatures $T_1$ and $T_3$ is the sum of the thermo-emfs generated between $T_1$ to $T_2$ and $T_2$ to $T_3$.Mathematically,$e_{T_1}^{T_3} = e_{T_1}^{T_2} + e_{T_2}^{T_3}$.Given:$e_{0}^{100} = 200\,\mu V$$e_{0}^{32} = 64\,\mu V$$e_{32}^{70} = 76\,\mu V$We need to find $e_{70}^{100}$.Using the additive property:$e_{0}^{100} = e_{0}^{32} + e_{32}^{70} + e_{70}^{100}$$200 = 64 + 76 + e_{70}^{100}$$200 = 140 + e_{70}^{100}$$e_{70}^{100} = 200 - 140 = 60\,\mu V$.
