Question

If the susceptibility of a paramagnetic substance at a temperature of \(23^\circ C\) is \(2.3\times10^{-5}\), then its susceptibility at a temperature of \(467^\circ C\) is:

• A. \(2.3\times10^{-6}\)
• B. \(6.9\times10^{-6}\)
• C. \(9.2\times10^{-6}\)
• D. \(4.6\times10^{-6}\)

Hint:

For paramagnetic substances: \[ \chi \propto \frac{1}{T}. \] Always convert temperature into Kelvin before applying Curie's law.

Answer 1

The Correct Option is C
