摘要
利用手持技术监测铁与水蒸气反应中供水剂和铁粉的温度变化,发现所选供水剂供水温度均在100℃以下,铁与水蒸气反应温度在500～600℃之间.基于此规律任选了一种常见的能吸附水的材料——黏土进行该实验,获得了很好的实验效果,验证了该规律的正确性.
Using hand-held technology, this paper measured the temperature changes of providing water reagents and iron powder in the reaction between iron and water vapor. It was found that the temperatures of the providing water reagents were under 100 ℃, and the reaction temperature was about 500～600 ℃. Based on this, this article selected clay which could absorb water easily to do the experiment and achieved good results, which indicated the law was right.
