围绕铁丝在氧气中燃烧的影响因素设计探究实验,重点探究氧气浓度、接触面积对铁燃烧的影响,同时探究铁丝燃烧过程中产生火星四射现象与铁丝中含碳量的关系。
Based on the factors that affect the combustion of iron wire in oxygen, an exploratory experiment was designed to investigate the influence of oxygen concentration and contact area on the combustion of iron. At the same time, the relationship between the sparking phenomenon and the carbon content in the iron wire was explored.
