One kilogram of liquid iron will have greater entropy.

#### Work Step by Step

A liquid is less ordered than the same substance in solid form. Also, heat is added to solid iron to change it to liquid iron. By equation 15-8, $\Delta S = \frac{Q}{T}$, the change in entropy will be positive. The entropy of the solid iron increases as heat is added and it turns liquid.
