A magnetic substance has a susceptibility -0.05 at 300 K. The magnetic susceptibility at 600 K is: |
-0.025 -0.1 -0.05 -0.5 |
-0.1 |
The correct answer is Option (2) → -0.1 As material behaviour follow the Curie-Weiss law - $\frac{X_2}{X_1}=\frac{T_2}{T_1}$ $⇒\frac{X_2}{-0.05}=\frac{600}{300}$ $⇒X_2=-0.1$ |
