How is crystallization temperature and melting point related? How is the amount of heat released during crystallization

How is crystallization temperature and melting point related? How is the amount of heat released during crystallization of a substance related to the amount of heat absorbed during its melting? Explain why.

The melting and crystallization temperatures are equal, the amount of heat absorbed during melting and the amount of heat released during crystallization are also equal. Crystallization produces the same substance. which was melted, with the same internal energy.
