Passing Gases: Effusion, Diffusion and the Velocity of a Gas - Crash Course Chemistry

The video explores the behavior of gases, focusing on velocity, kinetic energy, and the factors affecting them. It introduces Graham's Law of Effusion, explaining how gas particles move through barriers and how their mass affects their rate of effusion. The video also covers diffusion, demonstrating with an experiment using ammonia and hydrochloric acid to show how gases spread and react. Key concepts include the relationship between temperature, mass, and velocity, and how these principles apply to real-world scenarios.

What happens to gas particles when they collide with each other?

In what way does the mass of a gas affect its rate of effusion?

How do gases behave when allowed to move freely in a container?

What is the significance of the concentration gradient in gas movement?
