WebbThus, the particle model can be used to explain the properties of solids, liquids, and gases. It can also be used to explain what happens in changes of state (Figure 1 on the next … WebbThe first chapter of The Feynman Lectures on Physics is about the existence of atoms, which Feynman considered to be the most compact statement of physics, from which science could easily result even if all other knowledge was lost. By modeling matter as collections of hard spheres, it is possible to describe the kinetic theory of gases, upon …
Webb31 maj 2024 · In condensed matter systems, intricate interactions between electrons and nuclei are simplified by using a concept of the quasi-particle. In such description, the electron is considered as a dressed free electron, and its motion is described by replacing the electron mass with an effective mass. This simplification successfully describes ... Webbpictorial representations of the particle model. In recent times, Harrison and Treagust (2002) have argued for more research at senior and post-secondary level that would inform practice, as to how a more enriching and perhaps slower development of the concepts of the particulate nature of matter should be introduced
