solvent evaporation

Solvent evaporation occurs when a liquid solvent, like water or alcohol, transforms into a gas and escapes into the air. This process happens when molecules at the surface gain enough energy—often from heat or air movement—to break free from the liquid. As the solvent evaporates, the remaining substance, such as paint or adhesive, becomes thicker or dries out. Evaporation is essential in processes like drying paint, removing water from food, or sterilizing medical instruments, and it depends on factors like temperature, airflow, and the properties of the solvent itself.
