Notes
The specific heat values, including isobaric specific heat () and isochoric specific heat (), vary with temperature. At high temperatures above 1500 K, dissociation of oxygen gas becomes appreciable, making pressure a significant variable in specific heat calculations. The tabulated values apply to undissociated states.
