  abstractNote={<jats:p>The paper deals with the calculation of the gravitational entropy in the context of teleparallel gravity for de Sitter space-time. In such a theory it is possible to define gravitational energy and pressure; thus we use those expressions to construct the gravitational entropy. We use the temperature as a function of the cosmological constant and write the first law of thermodynamics from which we obtain the entropy. In the limit <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mi mathvariant="normal">Λ</mml:mi><mml:mo>≪</mml:mo><mml:mn mathvariant="normal">1</mml:mn></mml:math> we find that the entropy is proportional to volume, for a specific temperature's choice; we find that <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M2"><mml:mi mathvariant="normal">Δ</mml:mi><mml:mi>S</mml:mi><mml:mo>≥</mml:mo><mml:mn mathvariant="normal">0</mml:mn></mml:math> as well. We also identify a phase transition in de Sitter space-time by analyzing the specific heat.</jats:p>},
