12. The kinetic theory explains the behavior of particles in different states of matter by stating that particles are in constant motion. In solids, particles vibrate around fixed positions, while in liquids, they move more freely but remain close together. In gases, particles move rapidly and are far apart from each other.13. When a substance changes from solid to liquid, particles gain energy and vibrate more vigorously, weakening the bonds between them. This causes the particles to move more freely, resulting in a change of state. When a substance changes from liquid to gas, particles gain even more energy and move rapidly, breaking free from the bonds holding them together. This allows the particles to spread out and occupy a larger volume, resulting in a change of state.14. Plasma is the most common state of matter in the universe because it is formed under extreme conditions of high temperature and pressure. Stars, including our sun, are primarily composed of plasma. The intense heat and pressure in these celestial bodies cause atoms to ionize, creating a collection of charged particles. This state of matter is prevalent throughout the universe, making plasma the most common state of matter.
