Open in App
Solution
Fusion means the change of phase from solid to liquid state.
Entropy change for fusion is almost always positive since the degree of disorder increases in the transition from an organized crystalline solid to the disorganized structure of a liquid.
The only known exception is helium.
Hence, the statement given is true.
