How tiny particles dictate the world we see and touch

GCSE Chemistry - States of Matter & Changing State · 4:22 · Video: Cognito · Watch at the source

In short: Why does a solid hold its shape while a gas fills a room? This video breaks down 'particle theory' to explain the behavior of matter at a microscopic level.

The video explores the three primary states of matter—solid, liquid, and gas—by examining how particles behave, move, and interact. It provides a foundation for understanding phase changes, showing how substances transition between states based on particle dynamics.

For advanced learners, the content also addresses the specific limitations of particle theory, offering a more nuanced look at the scientific model used to describe the physical world.
