摘要: 通过实验发现充有空气的气球放人液氮后并不会发生爆炸,也不会只收缩成更小的气球,而是不断被压扁直至压平,通过与充有氮气的气球对比,并对气球中各种成分在低温下性质的分析,本文给出了该现象的合理解释,澄清了一些错误观点.

关键词: 液氮, 相变, 低温现象

Abstract: An experiment of a balloon being put in liquid nitrogen has been done balloon will not implode or explode or shrink to a small balloon, but be crashed to flat explanation of what had happened in this experiment. The results showed that the instead. We gave an explicit
