Give one assumption of the Kinetic Molecular Theory of Gases
1.Gases are composed of molecules that move in constant random motion.
2.The molecules have no definite volume, but they have a definite mass.
3.Each molecule moves in a straight line until it collides with another molecule or the walls of the container.
4.The collision between the molecules is completely elastic.
5. There is no attractive force among the molecules
6.The average kinetic energy of the gas molecules depends only on the temperature of the gas.
