Evaporation transfers molecules from a liquid surface into the surrounding vapour. It can occur below the boiling temperature, and competes with condensation from the vapour. Its net rate depends on the surrounding vapor pressure and transport conditions. Removing latent heat through evaporation can cool the remaining liquid.
Nonuniform accumulation of suspended material toward the edge of a drying drop, commonly when a pinned contact line and nonuniform evaporation drive outward liquid flow. Contact-line motion, solvent choice, drying conditions and ink formulation can alter or suppress the resulting deposit.

Evaporation is the process by which molecules of a liquid gain enough energy to transition into the gas phase. It occurs at the surface of the liquid and can happen at any temperature, although it happens more quickly at higher temperatures. In evaporation, individual molecules escape from the liquid into the air, where they disperse as vapor. Factors that influence the rate of evaporation include: 1. **Temperature**: Higher temperatures increase the kinetic energy of molecules, leading to a higher rate of evaporation.
