我们知道,气体对容器壁产生的压强是大量气体分子频繁碰撞器壁,使器壁受到一个平均持续的冲力而产生的,由此衍生出这样的一个问题:气体分子在单位时间对单位面积器壁的碰撞次数,跟气体的压强、温度有什么关系?这样的问题在高考题的选择题中进行了考查,得分率相当低.究其原因,是此问题已经稍微超出中学物理的教学要求,其理论依据要用到大学普通物理中的相关知识.由于高中物理教材配套的练习中有类似
We know that the gas pressure on the container wall is a large number of gas molecules collide with the wall, the wall is an average sustained momentum generated by the resulting derived from such a problem: gas molecules per unit time on the unit area The number of collisions with the wall, with the gas pressure, temperature, what is the relationship between? This problem in the multiple choice test questions were examined, the scoring rate is quite low. The reason is that this problem has slightly exceeded the physics teaching requirements, Its theoretical basis to use the university general physics related knowledge.Because high school physics teaching materials supporting the practice of similar
