How can heat melt solids without changing the temperature?

I’m trying to understand heat of fusion and I just can’t find myself on understanding how something can melt without changing the temperature?

Answer 1

I take it you mean at the point at where it melts and not the entire process.

It’s because at a certain point any extra heat you add will cause molecules to change from being part of the solid to leaving the solid. The extra energy causes them to go bye bye rather than raising the temperature because they have enough energy to now leave.
