Bond Enthalpy

When doing a question regarding bond enthalpy, would there ever be a time where the molecules were not in their gas state? How would one go about converting a molecule into its gas state?

I think if the molecules aren't in their gas state, you would use the values given of the enthalpy of formation for whatever state they are in to calculate bond enthalpy.
