The susceptibility of magnesium at 300 K is 1.2 x 10–5. At what temperature will the susceptibility increase to 1.8 x 10–5? |

Answer» Given : x1 = 1.2 x 10-5, T1 = 300 K, x2 = 1.8 x 10-5 To find: Required temperature (T2) Formula: xT = constant Calculation: From formula, x1T1 = x2T2 ∴ T2 = \(\frac{\chi_1T_1}{\chi_2}=\frac{1.2\times10^{-5}\times300}{1.8\times10^{-5}}\) ∴ T2 = 200 K Ans: The required temperature is 200 K. |
