Question

Which statement is TRUE in describing what occurs when a solid melts to a liquid? The process is endothermic and the heat of fusion is negative. The process is endothermic and the heat of fusion is positive. The process is exothermic and the heat of fusion is negative. The process is exothermic and the heat of fusion is positive. not enough information

Answer 1

Answer: The process is endothermic and the heat of fusion is positive

Explanation:

All solids absorb heat as they melt to become liquids. The gain of heat in this endothermic process goes into changing the state rather than changing the temperature
