Matter and the Particle Model

General objective of this lecture is to present on Matter and the Particle Model. Matter is anything that moves and anything that takes up space. Solids, Liquids and Gases. Here briefly focus on how does matter change. Finally explain on  the particle model. All substances are made up of particles (atoms, ions or molecules). These particles are attracted to each other, some strongly and others weakly. These particles move around (i.e. have kinetic energy). The kinetic energy of particles increases with temperature.
