    When a solid is converted into liquid, entropy 

    A)  becomes zero  

    B)  remains the same

    C)  decreases      

    D)  increases        

    Correct Answer: D

    Solution :

    Entropy is the measure of degree of randomness. As the randomness increases, entropy increases. In gases, molecules are randomly arranged while in solids molecules are arranged in orderly manner. Hence, the order of randomness is, \[gas>liquid>solid\] \[\therefore \] When a solid is converted into liquid, entropy increases.
