Some helpful advice to you:
1. Learn what an MSDS is. It will provide for you some basic physical and chemical properties of a given compound, as well as safety and handling procedures. While you're at it, get familiar with a CRC, and / or the Merck Index. Same info, same reasons.
2. Learn the proper definition of freezing point and melting point. You will find them to be identical. In this case, the value is 48.5 deg. C.
With this knowledge and just a SLIGHT amount of effort, you would have found this information online in about 2 minutes (perhaps less). I use the MSDS's at Fisher Scientific, so I know straight where to go.
Follow that advice if you are going to handle or work with chemicals even in the classroom.

Yeah, the MSDS has a lot of good stuff.
Fisher Scientific's website is free. You do have to make up an account but you can use, Joe Smith, whatever.
