The other answer is right but I just wish to clarify a point because I see this error all over the place.
There is a strong misconception that melting point and freezing point happen at the same temperature. It all practicality they do, in almost all practical experimentation they should be treated as such, and 99.9999% of the time its the same.
However, when we get away from bulk chemistry and get to the small scale, there can be variations, see this paper for example.
Also, I did read about one super cooled bulk material that had a difference in intermediate crystal structures going from liquid to solid vs solid to liquid that actually resulted in a difference in the two temperatures. I can not find that article now, but it's out there somewhere.
Again, these are extreme examples, but to truly say melting and freezing point are the same is technically wrong. I just needed to put this out there now.
It's also an important distinction because there is a directional component to the energy vector by saying either melting point or freezing point. (endothermic vs exothermic), although I guess "point" implies otherwise, but I find differentiating the two helps when understanding which state you started from.
