  We study thermodynamic properties of Myers-Perry black holes by deriving
explicit fundamental relations from which we can obtain the temperature and
specific heat in terms of explicit control parameters in arbitrary dimensions.
Using the definition of extremal black holes we establish the generalized Kerr
bound in arbitrary dimension. We study thermodynamic geometries of the
Myers-Perry black holes with equal angular momenta in arbitrary dimensions and
draw thermodynamic cone diagrams which capture the extremal limits of the black
holes. Thermodynamic state space is represented geometrically as a wedge
embedded in Minkowski space. The opening angle of such a wedge is uniquely
determined by the number of spacetime dimensions and the number of angular
momenta. Our results can potentially be used to generalize thermodynamic
instability analysis and other studies in which extremal limits of the
Myers-Perry black holes are required.
