32 is freezing point so 32 would be melting point
but if its under pressure or in a vacume it chainges the whole thing higher pressure lowers the freeze point
this is how ice skates work as the ice melts under the blade thain re freezes quickly
For some pure substances, such as pure water, the freezing temperature is lower than the melting temperature. The freezing point for water is only the same temperature as the melting point when nucleators are present to prevent supercooling. The freezing point of water is 0°C (32°F, 273 K). In the absence of nucleators water will supercool to as low as −70°C (−94°F, 203 K) before freezing. [1] But in the presence of nucleating substances the freezing point of water is the same as the melting point. Nucleating agents, such as dust, are commonly present in the environment, which is why rain water and tap water will normally freeze at the melting point of water.

wen it is at exactly 0C it is both the melting and freezing point.
it reaches an equilibrium where as one bit is just freezing another bit is just melting.
most people think thats bull s**t but the fact of the matter is, its true
because of the inner workings of the compund - with the intermolecular forces - the minimum energy for it to become a liquid is equal to the maximum energy of it staying a solid
blame hydrogen bonding lol

o C !
the Celcius scale is made from the water frozing time....
at 0 water become frozen ( I don't reemmber da proper word)
so everythign over 0 makes melting!

0 c or 32 f or 273 k (all the same temperature on different scales)

33 degrees Farenheit and 1 degree Celcius. The other 2 answers are the FREEZING points!

It depends on pressure.
0°C at standard pressure (100000 pascals)

Have you forgotten what your old science teacher taught you so soon?
It is 31.99 degrees F. Anything above that temperature and it freezes.
