Curie's Law -

\chi_{m}= \frac{C}{T}

- wherein

C- Curie constant which depends upon the nature of the substance

T- absolute temperature

Suspectibility = X

Then X\propto \frac{1}{T_{e}}

So \frac{X_{1}}{X_{2}} = \frac{T_{e2}}{T_{e1}}

T_{c}_{2}=300K, T_{c}_{1}=350K

X_{1}= 2.8 \times 10^{-4}

X_{2}= X_{1}(\frac{T_{c1}}{T_{c2}})=2.8\times 10^{-4}\times \frac{350}{300}

X_{2}\approx 3.3\times 10^{-4}

 


Option 1)

3.726 X 10-4

Option 2)

3.672 X 10-4

Option 3)

3.267 X 10-4

Option 4)

2.672 X 10-4
