Question

For this question, use the main assumptions of the Kinetic Molecular Theory of gases:

Answer 1

The correct answer is 3. The molecular collisions are perfectly elastic.

Explanation- The rapidly moving particle of gas collides with the walls of the container. All these collision are perfectly elastic. The pressure exerted by the gas is due to this continuous collision and the force experienced per unit area of the walls of the container determines the pressure exerted by the gas.

Answer 2

Answer:

Option 3 is correct.

3. The molecular collisions are perfectly elastic.

Explanation:

According to the kinetic molecular theory, the molecular collisions are perfectly elastic, so the the molecules of a gas striking with the wall of container are elastic and they are exerting considerable pressure on the walls of container. This pressure is actually exerted against the walls is less for real gases as compared to ideal gases.
