1.	The velocity of a gas molecule is comparable to that of a rifle bullet. Yet, a gas molecule spends a much longer time than a bullet does to travel equal distances .Explain.
Answer» Solution :A gas molecule suffers multiple collisions with the other molecules in the gas. As a result, it cannot move straight but TRAVELS any finite distance along a random zig-zag PATH. On the other hand,a rifle BULLET is MUCH heavier than gas molecules. Collisions with very light air molecules cannot after the straight path of the bullet. So the bullet travels a finite distance in a much shorter TIME.
