What should you know about the particle model of matter? Students come to see the particle model as more useful than a continuous model only gradually, therefore they should observe a range of phenomena which require the particle model to help explain them. Which is more useful, a particle model or a continuous model? Essentially the particle model is a way of thinking about matter that requires exploratory discussion to help build student understanding. Presenting this scientific view through the use of diagrams and models alone has been shown to achieve relatively little conceptual change in students. How is the particle theory presented to students? The model is used to explain the physical properties of solids, liquids and gases. The particle theory of matter is a model that describes the arrangement and movement of particles in a substance. Particles are often molecules whose shape is not a sphere, some of which are long chains of atoms. The particle model only explains the properties of solids, liquids and gases but not why different materials are solid, liquid or gas at different temperatures.
What properties can be explained by the particle model? The model could not explain the photoelectric effect, the color of hot objects, and the emission spectra. The particle model treat lights as if it were made of protons. What phenomena can only be explained by the particle? The wave model treats light as an electromagnetic wave. What phenomena can only be explained by particle model?
