    Using equipartition of energy, the specific heat (in \[J\,k{{g}^{-1}}{{K}^{-1}}\]) of aluminium at room temperature can be estimated to be (atomic weight of aluminium = 27)

    A) 410                  

    B)        25   

    C) 1850                

    D)        925

    Correct Answer: D

    Solution :

    [d] Using equipartition of energy, we have \[\frac{6}{2}KT=mCT\] \[C=\frac{3\times 1.38\times {{10}^{-23}}\times 6.02\times {{10}^{23}}}{27\times {{10}^{-3}}}\] \[\therefore \] \[C=925\,\,J/kgK\]
