Thermodynamic behavior of time-dependent wormholes in Palatini f(R) gravity

In the frame work of Palatini approach to modified f(R) theories gravity, we attempt investigate thermodynamic behavior time-dependent wormhole geometries. By considering an evolving spacetime, find field equations in gravity. The energy density and pressure are redefined order satisfy continuity equation. To discuss behavior, expression for variation total entropy is obtained. Then, extend our discussions apparent event horizons wormholes. We employ radius determine validity generalized second law thermodynamics which states that non-negative.
