Magnetic susceptibility of Mg at 300 K is 1.2 10⁻⁵ . What is its susceptibility at 200 ~K ?

Options

  1. A18 10⁻³
  2. B180 10⁻⁵
  3. C1.8 10⁻⁵
  4. D0.18 10⁻⁵

Correct answer

C. 1.8 10⁻⁵

Step-by-step solution

We know that magnetic susceptibility. 1 T ₂ ₁ = T₁ T₂ ₂= T₁ T₂ ₁=1.2 10⁻⁵ 300 200 =1.8 10⁻⁵
