Thermodynamic process in which the temperature is varying in space but its variation in time is much slower than other dynamic processes so that temperature can be considered as constant at any spatial location
:
T({\bf r}, t) = T({\bf r}) \Leftrightarrow \frac{\partial T}{\partial t} = 0 |
In specific case when the temperature is not varying in space:
the Quasi-isothermal process is called Isothermal.
