We consider a universe filled by a modified generalized Chaplygin gas together
with a pressureless dark matter component. We get a thermodynamical interpretation for
the modified generalized Chaplygin gas confined to the apparent horizon of FRW universe,
whiles dark sectors do not interact with each other. Thereinafter, by taking into account
a mutual interaction between the dark sectors of the cosmos, we find a thermodynamical
interpretation for interacting modified generalized Chaplygin gas. Additionally, probable
relation between the thermal fluctuations of the system and the assumed mutual interaction
is investigated. Finally, we show that if one wants to solve the coincidence problem by using
this mutual interaction, then the coupling constants of the interaction will be constrained.
The corresponding constraint is also addressed. Moreover, the thermodynamic interpretation
of using either a generalized Chaplygin gas or a Chaplygin gas to describe dark energy
is also addressed throughout the paper.
