GCSE Chemistry - States of Matter & Changing State #21

The video explains the states of matter—solid, liquid, and gas—using particle theory. It describes how particles behave in each state and how substances transition between states through heating and cooling. The video also discusses the limitations of the particle model, noting that it simplifies complex interactions between particles.

What happens to gas particles when they are heated?

Discuss the limitations of the particle model used to explain the states of matter.
