Chapter 16 Kinetic Theory of Gases 分子按位置的分布是均匀的dNN (C)At equilibrium, velocity of each molecule has the same probability to point to any directions. That is, the distribution of velocity of molecules is uniform in direction. which leads to the mean square speeds of all components of velocity are same 分子各方向运动概率均等,即分子按方向的分布 是均匀的。Chapter 16 Kinetic Theory of Gases V N V N n = = d d 分子按位置的分布是均匀的 (C) At equilibrium, velocity of each molecule has the same probability to point to any directions.
