Question

when u heat/burn iron rod it cant burn frequently but iron flings are burn frequently during heating give scientific reason​

Answer 1

Answer:

Iron has a strong molecular force of attraction. Hence when heated it doesn't reach to its ignition temperature and doesn't burn. But iron fillings when sprinkled in flames attain the ignition temperature ( as iron fillings are comparatively smaller particles) and gain larger surface area for the reaction.
