H2 O2 Some time after Stopcock closed Stopcock open Stopcock open (a) (b) (C) Figure 9.27 (a) Two gases, H2 and 02, are initially separated. (b) When the stopcock is opened, they mix together. The lighter gas, H2, passes through the opening faster than O2, so just after the stopcock is opened, more H2 molecules move to the O2 side than O2 molecules move to the H2 side. (c) After a short time, both the slower-moving Oz molecules and the faster-moving H2 molecules have distributed themselves evenly on both sides of the vessel. 예
