Changes of state refer to the transformations between different phases of matter: solid, liquid, gas, and plasma. These changes occur when energy is added or removed, affecting the arrangement and movement of particles. For example, melting occurs when a solid absorbs heat, causing its particles to move more freely and transition into a liquid. Conversely, freezing occurs when a liquid loses heat, leading to a more ordered arrangement of particles as they form a solid.
