d
\(\mathrm{R}=\mathrm{R}_0(1+\alpha \Delta \mathrm{T})\)

\(\frac{\Delta \mathrm{R}}{\mathrm{R}_0}=\alpha \Delta \mathrm{T}\)

Case-I

\(0{ }^{\circ} \mathrm{C} \rightarrow 100^{\circ} \mathrm{C}\)

\(\frac{10.2-10}{10}=\alpha(100-0)\)

Case-II

\(0^{\circ} \mathrm{C} \rightarrow t^{\circ} \mathrm{C}\)

\(\frac{10.95-10}{10}=\alpha(t-0)\)

\(\Rightarrow \frac{t}{100}=\frac{0.95}{0.2}=475^{\circ} \mathrm{C}\)

\(t=475+273=748 \mathrm{~K}\)
