页2、文娱演出时，舞台上往往要用弥漫的白烟雾，给人以假设隐假设现的舞台效果，这种烟雾实际上是()C.利用干冰升华吸热，使空气放热液化成的“雾D.利用干冰升华吸热，使空气中的水蒸气放热液化成的“雾选题目的：通过此题教会学生应用升华、液化分析生活实例。分析：在舞台上喷洒干冰，固态二氧化碳迅速升华，要吸收大量的热量，从而使周围温度降低，空气中的水蒸气遇冷放热液化成细小的水珠悬浮在空气中，这就是我们看到的“白雾。假设喷射真实的烟雾，会污染环境，故A 错;二氧化碳无色透明，根本看不到，故B错;要使空气液化需要极低的温度，也不现实，故C错。答案：D.3、“草地结露与“草地结霜各是什么现象?选题目的：通过此题让学生认识自然中的液化和凝华现象。分析：在夜间气温降低时，飘逸在空气中的水蒸气遇冷就在草木上液化成小水珠，这就是“露。当夜间气温突然降低，降低到 0以下时，空气中的水蒸气直接凝华成小冰晶，|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 3 页，共 4 页文档编码:CW4K9P4Y2D4 HY1F1Y9K8L8 ZH5G5U5U5Q9文档编码:CW4K9P4Y2D4 HY1F1Y9K8L8 ZH5G5U5U5Q9文档编码:CW4K9P4Y2D4 HY1F1Y9K8L8
