Q61
The dependences of the magnetic susceptibility ( ) of a material with temperature (T) can be represented by 1T - , where θ is the Curie-Weiss temperature. The plot of magnetic susceptibility versus temperature is sketched in the figure, as curves P, Q and R with curve Q having θ = 0. Which one of the following statements is correct?
