综合性实验试题是高考理综试卷的必考题目，其兼有考查学生实验能力、知识运用能力、创新能力的多重功能，也特别成为体现学科间综合的热点。气体压强问题是物理学科知识，但却和许多化学实验有关，尤其体现在气体的制备、收集、除杂及喷泉实验中，复习实验时要注意体会和总结? Comprehensive test questions are required for the college entrance examination science examination papers. They combine the multiple functions of examining students’ experimental abilities, knowledge utilization abilities, and innovation abilities. They also become particularly hot topics that reflect interdisciplinary integration. The problem of gas pressure is a knowledge of physics, but it is related to many chemical experiments, especially in gas preparation, collection, impurity removal, and fountain experiments. We must pay attention to the experience and summary when reviewing experiments.
