Usage of 溶解 (róngjiě)

溶解 primarily means 'to dissolve' or 'to melt' in a physical or chemical context. It is commonly used when describing substances dissolving in liquids or solids melting due to heat.

Common contexts

  • Chemistry: describing how solids dissolve in solvents.
  • Everyday life: ice melting or sugar dissolving in tea.

Collocations and patterns

  • 溶解固体 (róngjiě gùtǐ): dissolve solids, often used in scientific contexts.
  • 溶解 (róngjiě zài shuǐ zhōng): dissolve in water, a frequent phrase.

Notes

溶解 is more formal and scientific than just (to melt/dissolve). It is not used metaphorically for explaining or solving problems despite the character meaning 'to explain'. Avoid confusing 溶解 with (to untie or solve).
