Can you use melting point to determine the identity of an unknown solid?
A piece of gray metal appears to be melting.
The metal is observed to begin to melt when the temperature of its container is approximately 29°C. The metal is most likely

Yes — comparing a substance's observed melting temperature to known melting points can identify it.
Since the sample begins to melt at about 29°C and the list gives gallium a melting point of 29.78°C, the metal is most likely gallium. (The other metals listed melt at much higher or much lower temperatures.)
