Particles of matter

Arrangement of particles in matter depends on its phase. They're close and organized in solids, close but irregular in liquids, and far apart and irregular in gases.

Solids, liquids and gases are three states of matter. In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gases, they are spread out. Particles in chemistry can be atoms, ions or molecules.

What is meant by the Kinetic Theory of Matter? The Kinetic Theory of Matter: The arrangement and movement of particles in solids, liquids and gases are described in the kinetic theory of matter. The kinetic theory of matter is used to explain the changes in the states of matter. The changes in the states of […]

The phase changes of matter include melting, freezing, evaporation, condensation, deposition, and sublimation.

Siyavula's open Natural Sciences Grade 8 textbook, chapter 6 on Particle model of matter covering 6.1 What is the particle model of matter?

The goal of this activity is to develop and use a model to describe that matter is made of particles on a scale that is too small to be seen. You will be making observations of changes supported by a particle model of matter. This activity covers UT SEEd Strand 5.2.- All substances are composed of matter. Matter is made of particles that are too small to be seen but still exist and can be detected by other means.

​​ The kinetic particle theory explains the properties of the different states of matter. The particles in solids, liquids and gases have different amounts of energy. They are arranged...

The three classical states of matter compared at the molecular level. In solids, the particles vibrate about fixed positions. In liquids, the particles vibrate and move over and in between one another. Gas particles are widely spaced and move with rapid, random motion.
