The word 融化 (rónghuà), meaning "to melt" or "thaw", is formed by combining two characters that each contribute a layer of meaning related to transformation. The first character, 融, carries the core concept of blending, dissolving, or fusing, often with a connotation of harmony. The second character, 化, means to change or transform into a different state. When placed together, they create a vivid, composite idea where 融 provides the specific action of liquefying or merging, and 化 reinforces the overarching process of change, resulting in a term that perfectly encapsulates the transition from a solid to a liquid state.
