Changes of State

Changes of state refer to the fundamental transitions that matter undergoes, shifting between solid, liquid, and gas forms. This process, governed by principles of thermodynamics, is a cornerstone of physical science. When a substance gains or loses energy, its molecular arrangement alters, leading to distinct properties and behaviors. For instance, as ice melts into water with increased thermal energy, molecules break free from their rigid structure. Similarly, when water boils into vapor, molecules gain enough energy to overcome intermolecular forces. Understanding these transformations is crucial not only for scientific inquiry but also for everyday applications, from cooking to industrial processes.
