A
Correct answer
Explanation
All elements can exist as gases at sufficiently high temperatures. Iron's boiling point is approximately 2862°C (5184°F). Above this temperature, iron transitions from liquid to gas phase. Phase depends on temperature and pressure - solid, liquid, and gas are just states of matter for the same substance.
AI explanation
Iron, like any element, can exist in a gaseous state if heated above its boiling point (around 2862°C / 5182°F) — this is how iron vapor forms in stars and in some industrial or lab processes. Everyday experience only shows iron as a solid, but that's a matter of typical conditions, not a hard limit on the element itself.
