According to the kinetic theory of gases, in an ideal gas, between two successive collisions a gas molecule travels:
In a circular path
In a wavy path
In a straight line path
With an accelerated velocity
According to one of the postulates of the kinetic theory of gases, it is described that gas molecules always travel in a straight line. These molecules collide with each other and with the walls of the container. Thus between two successive collisions, gas molecules travel in a straight line.
Therefore, Option (3) is correct
