    The latent heat of fusion of ice at \[0{{\,}^{o}}C\]is\[\text{80}\,\text{cal/g}\text{.}\]Entropy change \[\text{(}\Delta S\text{)}\] accompanying the melting of 1 g of ice at \[0{{\,}^{o}}C\]would be (units:\[cal/g/K\])

    A)  273            

    B)  8.0

    C)  0.0             

    D)  0.293

    Correct Answer: D

    Solution :

     \[\Delta {{S}_{mel}}=\frac{\Delta {{H}_{mel}}}{T}\] \[=\frac{80}{273}\] \[=0.293\,\text{cal/g/K}\]
