Webcific heat (at constant pressure) of a black hole Cto be determined. Substituting dQ = c2dmand from Eq. (2) dT= – 8 c k 3 G d m m 2 yields C= – 8 k c G M. The negative sign … Web5.We’re about to build a heat engine out of a black hole. But rst, prove a key result: adiabats and isochores must be the same for black holes. (!!!) 6.Use the fact that Q= T S along isotherms, together with the results of previous parts, to compute the e ciency of a black-hole Carnot engine, and con rm that you get the Carnot e ciency.
