The particle model of matter

The particle model of matter

Particle model comparison of solid, liquid, and gas showing spacing, arrangement, motion, and relative density

Matter is anything that has mass and takes up space. A particle is a tiny piece of matter, and in the particle model the arrangement and motion of particles explain the properties of solids, liquids, and gases.

  3. /1.1 The particle model

Step-by-step lessons on OCR GCSE Physics 1.1 The particle model, covering 1.1.1 Development of the atomic model, 1.1.2 Structure of the atom, 1.1.3 The size of atoms and small molecules, 1.1.4 Density, 1.1.5 Density and the states of matter, and 1.1.6 Density, mass and volume. Each one builds up to exam-style questions. Paper 2 and Paper 4 include synoptic questions that draw on Topics P1–P4, so revisit earlier topics before final exams rather than treating each paper as self-contained.
