Heat transfer at low rates of mass transfer
One very common case of low-rate heat and mass transfer is the evapora-
tion of water into air at low or moderate temperatures. ... mass

Coupling can arise when temperature-dependent mass transfer pro-
cesses cause heat to be released or absorbed at a surface. For example,
during evaporation, late...
