Abstract
A non-equilibrium picture of thermodynamics is discussed at the apparent horizon of FRW universe in f(R,T) gravity, where R is the Ricci scalar and T is the trace of the energy-momentum tensor. We take two forms of the energy-momentum tensor of dark components and demonstrate that equilibrium description of thermodynamics is not achievable in both cases. We check the validity of the first and second law of thermodynamics in this scenario. It is shown that the Friedmann equations can be expressed in the form of first law of thermodynamics ThdS'h+Thd𝚥S' = −dE'+W'dV, where d𝚥S' is the entropy production term. Finally, we conclude that the second law of thermodynamics holds both in phantom and non-phantom phases.
