Vedclass · Answer

(A) Tungsten is a paramagnetic material. According to Curie's Law,the magnetic susceptibility $\chi$ of a paramagnetic material is inversely proportional to its absolute temperature $T$,i.e.,$\chi \propto \frac{1}{T}$.Therefore,$\chi_1 T_1 = \chi_2 T_2$.Given: $\chi_1 = 6.8 	imes 10^{-5}$,$T_1 = 300 \ K$,$T_2 = 400 \ K$.Substituting the values: $(6.8 	imes 10^{-5}) 	imes 300 = \chi_2 	imes 400$.$\chi_2 = \frac{6.8 	imes 10^{-5} 	imes 300}{400} = 6.8 	imes 10^{-5} 	imes 0.75 = 5.1 	imes 10^{-5}$.

The susceptibility of tungsten is $6.8 \times 10^{-5}$ at temperature $300 \ K$. The susceptibility at temperature $400 \ K$ is
