yes but going from solid to gas reqires the Hf to be added. Same concept as when u compute the total Q reqired to take an ice cube at -10 C to 110 C. You compute the energy needed to bring ice from -10 C to 0, then the H at 0 (the plateau), then 0 to 100, then the H at 100, then 100 to 110. The solid state of C is 0, but the H of formation of C gas reqires energy, a change of state.
