Is freezing endothermic? Thermodynamics provides insights into this question. Endothermic and exothermic processes involve heat transfer. Exothermic processes release heat, while endothermic processes absorb it. Freezing is an endothermic process because it requires heat absorption to break intermolecular bonds and transition from a liquid to a solid phase. Understanding such concepts is crucial for comprehending the behavior of matter and various physical and chemical transformations.
