Physics:Particle Model of Matter and Kinetic Theory of Gases
Have you ever wondered how water can exist as a solid which cracks in straight lines， or exist as liquid which can break into a million pieces and reform undamaged? How can it turn into a gas carrying so much energy? Why do gases become light when they are warm? How can we predict the behaviour of gases so we can use them to do our bidding. The explanation is simple， yet one of the greatest scientific discoveries of all time — matter is made up of particles.
