1.	The molecular speeds of gasesous molecules are analogous to those of rifle bullets. Then why is the odour of a gas not detected so fast ?
Answer» Solution :Though the molecules of a gas travel at HIGH speeds but they do not travel in straight lines in one direction like bullets. As they travel, they collide with the molecules of the gases PRESENT in the air. As a result, they are deflected. Thus, they follow a zig-zag PATH, i.e., the net distance travelled in a PARTICULAR direction is quite small in a given TIME. That is why the odour is not detected so fast.
