Query: Thermodynamics of Extended Gravity Black Holes   Thermodynamics of extended gravity static spherically symmetric black hole
solutions is investigated. The energy issue is discussed making use of the
derivation of Clausius relation from equations of motion, evaluating the black
hole entropy by the Wald method and computing the related Hawking temperature.
