Mass transfer is the phrase commonly used in engineering for physical processes which involve molecular and convective transport of
atoms and molecules within physical systems. Mass transfer includes both mixing and separation processes.
- Some common examples of mass transfer processes are the evaporation of
water from a pond to the atmosphere;
the diffusion of chemical
impurities in lakes, rivers, and oceans from
natural or artificial point sources; mass transfer is also responsible for the separation of components in an
apparatus such as a distillation column.

In astronomy, mass transfer is the process by which matter gravitationally bound to a body,
usually a star, fills its Roche lobe and
becomes gravitationally bound to a second body, usually a compact object (white
dwarf, neutron star or black hole), and is eventually accreted onto it. It is a common phenomenon in binary systems, and may play an important role in some types of supernovae, and pulsars.
