27、无机盐溶解于水时总的热效应就由这两部分的综合效应来决定。硝酸铵等少数盐类溶解时吸热特别强烈，因而是常用的化学制冷剂。实验用品：硝酸铵(NH4N03)(化肥或试剂)水保温瓶或保温饭盒 10 号铁丝 量筒(100 毫升)台秤 烧杯（200毫升）实验步骤：1将硝酸铵在台秤上称出几份，每份120克，分别装入小塑料袋，封口携带备用。2用 10 号铁丝弯成一铁丝支架，以备放置待保鲜致冷的食品。3使用时先用烧杯盛100毫升水，然后将硝酸铵全部次倒入烧杯中，不要搅拌。文档编码:CP6T10B6O7D10 HD9G6R3A4O2 ZA1Y4N7W1U3文档编码:CP6T10B6O7D10 HD9G6R3A4O2
