The magnetic susceptibility of a paramagnetic substance at $- 73^{o} C$ is $0.0060$ , then its value at $- 173^{o} C$ will be

Options:

Answer:

Solution:

$χ_{m} \propto \frac{1}{T}$
$\Rightarrow \frac{χ_{m 1}}{χ_{m 2}} = \frac{T_{2}}{T_{1}}$
$\Rightarrow \frac{χ_{m 1}}{χ_{m 2}} = \frac{100}{200}$
$\Rightarrow {χ_{m}}_{2} = 2 {χ_{m}}_{1}$
$\Rightarrow {χ_{m}}_{2} = 2 \times 0.0060 = 0.0120$
