  • question_answer How will you justify that the collisions among the gas molecules are perfectly elastic?

    Answer:

                    According to the kinetic theory, the collisions of the gas molecules among themselves and also with the walls of the container are perfectly elastic. This means that the collisions are frictionless and there is no loss of kinetic energy in the collisions. Had it not been so, some energy might have been lost during each collision and the molecules must ultimately come to rest. But this does not happen. This clearly shows that the collisions are of elastic nature. However, the molecules may exchange energy during the collisions.
