Chapter 2 Structure of an Atom

Chapter 2 Structure of an AtomMatter is made up of tiny & discrete particles, which are constantly moving & poses kinetic energyThere are spaces btwn the particlesThe kinetic energy of particles change with temperature, the higher the temperature, the faster the particles moveAt a fixed temperature, lighter particles move faster than the heavier particlesKinetic theory of matterlighter particles move faster
