If a solid has a heat of fusion of 17.02 kj/mol and an entropy of fusion of 38.98 j/mol- k, what is the melting point in °c) of this pure solid? type your answer rounded to 1 decimal place without units (i. e. nn. n).

Explanation:

Melting point is defined as the point at which a solid substance starts to change into liquid state.

Whereas entropy is the degree of randomness of molecules present in a substance.

Heat of fusion is defined as the amount of heat energy necessary to melt a solid substance at its melting point.

Relation between entropy and heat of fusion is as follows.

where,           = 38.98 J/mol K

                      = 17.02 kJ/mol

                                    =

                                    = 17020 J/mol

Therefore, calculate the melting point as follows.

                           38.98 J/mol K =

                              T = 436.63 K

Change the temperature into degree celsius as follows.

                                 =

Thus, we can conclude that the melting point in is .

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

um i think it might be a car?
