Vedclass · Answer

(B) According to Curie's Law for paramagnetic substances,the magnetic susceptibility $\chi$ is inversely proportional to the absolute temperature $T$,i.e.,$\chi \propto \frac{1}{T}$.This implies $\chi_1 T_1 = \chi_2 T_2$.Given: $\chi_1 = 1.2 	imes 10^{-5}$,$T_1 = 300\, K$,and $\chi_2 = 1.8 	imes 10^{-5}$.Substituting the values: $(1.2 	imes 10^{-5}) 	imes 300 = (1.8 	imes 10^{-5}) 	imes T_2$.$T_2 = \frac{1.2 	imes 10^{-5} 	imes 300}{1.8 	imes 10^{-5}} = \frac{1.2}{1.8} 	imes 300 = \frac{2}{3} 	imes 300 = 200\, K$.

Susceptibility of $Mg$ at $300\, K$ is $1.2 \times 10^{-5}$. The temperature at which susceptibility will be $1.8 \times 10^{-5}$ is......$K$.
