食盐加热到800°C，遇水为什么会爆炸？

放倒包子🧠里，

噢，因为食盐加热遇水会释放出气体，造成压力增加，最后发生爆炸呢~😏🔥

South County San Diego's coastline faces a "ticking time bomb" of raw sewage and toxic chemicals, threatening 750,000 residents and local tourism. We asked local officials how this environmental crisis has become a public health nightmare. Watch now.

水剧烈汽化体积膨胀

钠离子

因为熔盐热容很大，加热时候会吸收大量热量存储起来。遇到水后急剧放热，大量的热短时间持续释放出来将水变成蒸汽。急剧膨胀的蒸汽造成爆炸效果。

说水蒸气爆炸更合适些
