The magnetic susceptibility of a paramagnetic material at -73^ C is 0.0075 . Its value at -173^ C will be

Options

  1. A0.0075
  2. B0.0045
  3. C0.0150
  4. D0.0030

Correct answer

C. 0.0150

Step-by-step solution

(C) 1 ~T ₁ ₂ = T ₂ ~T ₁ T₁=273-73=200, T₂=273-173=100 ₂= T₁ T₂ ₁= 200 100 0.0075=0.0150
