What is the term for the change from solid to liquid state?

The transition from a solid state to a liquid state is called melting. This process occurs when a solid absorbs heat, increasing the energy of its molecules. As the temperature rises, the molecular structure of the solid begins to break down, allowing it to flow as a liquid. Melting is a critical concept in various scientific fields, including chemistry and physics, and is essential for understanding phase changes in matter.

Other terms listed refer to different processes: freezing is the change from liquid to solid, condensation describes the process where a vapor turns into a liquid, and evaporation is the transition from liquid to gas. Each of these processes describes a unique change in state related to temperature and energy changes in materials.
