Question

The susceptibility of magnesium at 300 K is 1.2 $\times {10}^{-5}$. At what temperature will the susceptibility increase to 1.8 $\times {10}^{-5}$ ?

Answer 1

Since x = $\frac{C}{T}$

$\Rightarrow \frac{x_1}{x_2}=\frac{T_1}{T_2}$

$\Rightarrow \frac{1.2\times {10}^{-5}}{1.8\times {10}^{-5}}=\frac{T_2}{300}$

$\Rightarrow T_2=\frac{12}{18}\times 300$

= $\frac{2}{3}\times 300$ = 200 K
