某兴趣小组活动中,同学们按图1装置对“可燃物燃烧的条件”进行探究。探究过程中,大家对磷燃烧生成的大量白烟是否危害人体健康提出了疑问。【查阅资料】白磷的着火点是40℃,红磷的着火点是240℃,磷燃烧的产物五氧化二磷是白色固体,可能与空气中的水蒸气反应,生成 In an interest group activity, the students explored the conditions of combustibles burning according to the device of FIG. 1. In the process of inquiry, everyone raised questions as to whether a large amount of white smoke generated by phosphorus combustion would endanger human health. [Access to information] the ignition point of white phosphorus is 40 ℃, the ignition point of red phosphorus is 240 ℃, the product of phosphorus combustion phosphorus pentoxide is a white solid, may react with water vapor in the air to generate
