| One cannot imagine a comprehensive particle theory without several forms of matter. |
| The most prominent advocate of a particle theory of light was Isaac Newton. |
| It was time to find a theory of electromagnetic radiation that would fuse the wave theory and the particle theory. |
| Students will explore the properties of fluids, including viscosity and density, and explain them, using the particle theory. |
| Fundamental particle theory was tested in another way. |
| The particle theory and the kinetic molecular theory help students explain their observations and understand both the relationship between heat and temperature and the concept of heat capacity on a qualitative level. |
