What does “Kinetic molecular theory” actually mean in States of Matter: Gases, and why does it matter for JEE?
gases are tiny, fast, far-apart particles in constant random motion; pressure comes from their collisions with the walls.
In simple words: gases are tiny, fast, far-apart particles in constant random motion; pressure comes from their collisions with the walls. Getting Kinetic molecular theory clear matters because JEE questions on States of Matter: Gases usually test this idea directly, not just a formula you memorised.
Key point
Kinetic molecular theory
Common mistake
picturing gas molecules as touching or slow.
Memory tip
a gas is mostly empty space with fast, bouncing particles.
