Only in pure oxygen at high pressure does the metal burn with a bright flame to form the oxide. Similarly, it does not react with water either, since the insoluble gallium hydroxide is formed here. If, on the other hand, gallium is alloyed with aluminum and is liquid at room temperature due to the lowering of the melting point, it reacts very violently with water.
