Question

According to the kinetic theory of gases, in an ideal gas, between two successive collisions, a gas molecule travels:

• A. in a wavy path
• B. in a straight line path
• C. with an accelerated velocity
• D. in a circular path

Answer 1

The correct option is B in a straight line path

According to the postulates of kinetic theory of gases, the molecules of a gas move in a straight line between two successive collisions. They change their path only when they suffer collisions with the other molecules or with the walls of the container.
