Unit 2 Lesson 3 The kinetic theory of matter explains that matter is made up of particles‚ which are in constant motion resulting in the different states of matter. Matter is made of constantly moving particles‚ which tells us how the matter in solids‚ liquids‚ and gases behaves. When molecules bump into each other‚ they do not gain or lose energy‚ they only transfer it‚ so there is no net energy change (law of the conservation of energy). In a solid‚ molecules vibrate in a fixed position
