自从2002年《高中物理教学大纲》调整,把热学部分的“气体实验定律”和“理想气体状态方程”删掉后,气体压强的微观解释就成了该部分的重点内容.从宏观来讲,气体的压强由气体的体积和温度共同决定,这点比较好理解;从微观来讲,在气体压强一定的情况下,气体分子在单位时间内与器 Since the adjustment of the “High School Physics Teaching Syllabus” in 2002 and the deletion of the “Theory of Gas Experiments” and “The State Equation of Ideal Gases” in the thermal part, the microscopic explanation of the gas pressure has become the focus of this section. From the macro perspective, The pressure of the gas is determined by the volume and temperature of the gas, which is better understood; from the microscopic point of view, the gas molecules are in the unit time in the case of a certain gas pressure.
