同学们发现一种“氮气灭火装置”利用液氮沸点为﹣196℃产生大量氮气来灭火.他们用氮气进行如图所示实验却发现蜡烛未熄灭. 【査阅资料】氮气密度略小于空气压强不变时气体温度越低密度越大. 1结合氮气性质分析右图蜡烛未熄灭的原因可能是. 实验1探究氮气能否用来灭火所用容器均为隔热材料下同 2实验前有同学提出由液氮汽化产生的氮气温度低密度足够大会向下流动隔绝可燃物周围的氧气.依据实验1判断这种假设填“成立”或“不成立”. 3有同学根据实验1提出新假设氮气灭火可能与可燃物周围氮气的含量有关.可能支持这一假设的实验现象是填实验1中的实验编号. 实验2探究灭火与氮气含量是否有关 4实验2中蜡烛所在位置氮气含量最高的是填实验编号. 5推测实验2﹣3的现象是. 6反思实验2除氮气含量外影响蜡烛燃烧的其它可能因素是. 7结合上述实验下列关于“氮气灭火装置”使用的说法中合理的是填字母序号. A.从高处向低处喷洒使用 B.可燃物火焰熄灭后还需持续通气一段时间 C.在有少量排气口的封闭空间中使用时效果好于开放空间
