大气压是由于气体分子对物体表面的碰撞而产生的压力。大气中的任何物体都受到大气压的作用。令许多小学生困惑的是:我们身处大气压力下,却感觉不到它的存在。小学自然教材和一些教学参考资料列出了几个有关大气压的实验,这些实验有助于小学生对大气压概念的理解。但这些实验通
Atmospheric pressure is due to the gas molecules on the surface of the collision pressure. Anything in the atmosphere is subject to atmospheric pressure. What puzzles many primary schoolchildren is that while we are under atmospheric pressure, we do not feel the existence of it. Several primary textbooks and some teaching references have listed several experiments on atmospheric pressure that will help pupils understand the concept of atmospheric pressure. But these experiments pass
