What is the kinetic molecular theory of gases?

Here’s a simple explanation of the Kinetic Molecular Theory (KMT) of gases:

The theory explains how gas particles behave:

1. Gas particles are tiny and far apart – most of the gas volume is empty space.
2. Particles move constantly – in straight lines until they collide with each other or the container walls.
3. Collisions are elastic – no energy is lost when gas particles collide.
4. No attraction or repulsion – ideal gases assume particles don’t pull or push each other.
5. Temperature measures particle motion – higher temperature means particles move faster.

In short: Gas properties like pressure, volume, and temperature come from the motion and collisions of particles.
