    The susceptibility of a paramagnetic material is\[\chi \] at 27° C. At what temperature will its susceptibility be\[\frac{\chi }{2}\] ?

    A) 327° C                                      

    B) 54° C

    C) 237°C                                       

    D) 1600°C

    Correct Answer: B

    Solution :

    For paramagnetic material, \[x=\frac{1}{T}\] \[\therefore \]\[\frac{{{x}_{1}}}{{{x}_{2}}}=\frac{{{T}_{2}}}{{{T}_{1}}}\Rightarrow \frac{x}{x/2}=\frac{{{T}_{2}}}{27}\] \[27\times 2={{T}_{2}}\] \[{{T}_{2}}={{54}^{\circ }}C\]
