Answer #1

is the increase in entropy when a substance melts and is given as

= Hfusion/ Tf where Hfusion is the heat of fusion and Tf is the temperature at which melting occurs.

Thus Sfusion= Hfusion/1000   

i cannot arrive at the final answer, since you have not provided the value for delta H. You can just substitute H and get your answer. Answer will be positive since entropy (degree of randomness) increases as a substance changes from solid to liquid state (melting)
