Question

The $\chi -\left(\frac{1}{T}\right)$ graph for an alloy of paramagnetic nature is shown in figure. The curie constant is, then

• A. $57K$
• B. $2.8\times {10}^{-3}K$
• C. $570K$
• D. $17.5\times {10}^{-3}K$

Answer 1

The correct option is A $57K$

$X=C\times \frac{1}{T}=\frac{0.4}{1\times 7^{-3}}=57K$
