Kinetic Molecular Theory of Gas
What is Kinetic energy?
Energy of motion
Kinetic theory of gasesAssume molecules are point masses (possess mass but no volume)Constant random motion, collisions are completely elasticenergy can be transferred, but total energy remains the same. Gas molecules are neither attracted or repulsedSlide3
Kinetic Molecular Theory: Pressure
Pressure is created by collisions between molecules and the container. Slide4
Discussion Questions: Kinetic Molecular Theory
Do all your molecules hit the walls of their container with the same force? Justify your answer based on kinetic molecular theory. Slide5
Discussion Questions: Kinetic Molecular Theory
How does the frequency and force (respectively) of the collisions of the molecules of a gas with the walls of the container change as the temperature of the gas is decreased? Justify based on kinetic model of gases. Slide6
