要正确理解沸点与压强的关系，关键要认真观察课本133页图11－11演示实验，分析为什么停止沸腾的水在气压减小时会重新沸腾，研究这种现象产生的条件和原因，知道这个实验说明了什么问题．有关实验题的解题方法辅导例1烧瓶中的水被加热到沸腾，停止加热待水温降低一些后，将大?
To correctly understand the relationship between boiling point and pressure, it is critical to carefully observe the demonstration experiment in Figure 11-11 on page 133 of the textbook. Analyze why the boiling water stops boiling when the pressure is reduced. Study the conditions and causes of this phenomenon. Know the experiment. Explain what the problem is. How to Solve the Problem of the Experiment Tutorial Example 1 The water in the flask was heated to boiling, and the heating was stopped until the water temperature decreased.
