Tungsten tetrabromide (WBr4) and tungsten tribromide (WBr3) differ somewhat in their melting points. Below is a brief description of their melting points:
Melting point of tungsten tetrabromide:
Tungsten tetrabromide has a higher melting point of about 286°C (559°F). This means that at temperatures above 286°C, tetrabromotungsten melts into a liquid state. At room temperature, it is a solid substance.
Melting point of tungsten tribromide:
Tungsten tribromide has a low melting point of about 202°C (396°F). This means that at temperatures above 202°C, tungsten tribromide changes to a liquid state. Similar to tetrabromotungsten, tungsten tribromide is a solid at room temperature.
