Gas Diffusion Concept Map Overview

Diffusion in gases is the spreading of gas molecules from a region of higher concentration to lower concentration. Because gas particles move fast and freely, they mix quickly without any stirring. The topic divides into the particle model behind the process, the factors that change its speed, the mathematical relationship known as Graham's law, and real examples such as perfume spreading across a room.

Particle motion: random, constant movement of gas molecules with large spaces between them
Rate factors: molar mass, temperature and pressure that change how fast gases mix
Graham's law: rate of diffusion is inversely proportional to the square root of molar mass
Diffusion vs effusion: mixing through open space versus escape through a tiny hole
Everyday examples: smells spreading, bromine vapour mixing, and gases in the lungs

Use a map like this to revise before a test, then check your understanding by quizzing yourself. CogniGuide can build a personalized diffusion map from your own notes, so the branches match your course.

Diffusion in Gases Questions

Common questions about gas diffusion and how to build a map of it.

Why do lighter gases diffuse faster?

Lighter molecules have lower molar mass, so at the same temperature they move at higher average speeds. Graham's law states that the rate of diffusion is inversely proportional to the square root of molar mass, so the lighter gas spreads faster.

How does temperature affect gas diffusion?

Higher temperature gives gas particles more kinetic energy, so they move faster and diffuse more quickly. Lower temperature slows the process because the particles move more slowly.

Which files can I use to make a diffusion map?

You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images of your notes. You can also type a topic name instead of uploading anything.

Can I turn the diffusion map into a quiz?

Yes. Any map can be turned into a quiz to test yourself, and the same notes can also be made into flashcards. The free plan includes 5 creations a week with no payment needed.
