Description
Summary:This paper aims to study the thermodynamic features of the Reissner-Nordström-de Sitter black hole through the inner and outer horizons. We calculate different thermodynamic products such as area product, horizon radii product, Bekenstein-Hawking entropy product, Hawking temperature product, surface gravity product, Komar energy product, irreducible mass product, and specific heat product on inner and outer horizons of Reissner-Nordström-de Sitter black hole. We have found that all product formulae are dependent on black hole mass, and hence, they are not universal quantities. Furthermore, the thermodynamic stability of Reissner-Nordström-de Sitter black holes is discussed.
