Does temperature remain constant in diathermic process. Does the temperature remain constant in container with diathermic walls.

diathermic process is besically a process which allow the heat to exchange in and out of a container but not energy , 
in that case the temperature in diathermic process will not be constant as it allow the heat to flows out . temperature always floculates in the case of diathermic process. 
In thermodynamics, a diathermal wall between two thermodynamic systems allows heat but not matter to pass across it.,, 
and in there the temp. will remain constant , beacuse once the diathermic wall escapes the heat , then for regaining the heat it have to undergoes with some process , and that process is what we called as diathermic process, 
so, in the case of wall the temp. will remain constant inside , but in diathermic process it doesnot .
