Question

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

1. Gases are made up of molecules which are relatively far apart.
2. The molecules are in motion at high speeds.
3. The molecular collisions are perfectly elastic.
4. Increase in temperature increases the kinetic energy of the molecules.

Which of the assumptions explains the pressure which a gas exerts?

Answer 1

I took the quiz the correct answer is 2 and 4.

Step-by-step explanation:

Answer 2

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.
