Answer:

[tex]\boxed {\boxed {\sf Solid \ to \ liquid}}[/tex]

Explanation:

When heat is added to matter, the temperature rises. The average kinetic energy also increase and the matter melts.

When matter melts, it turns from a solid to a liquid. So, the melting point of matter is the temperature where it changes from the solid state of matter to the liquid state of matter.
