The question seems to be incomplete or incorrectly framed. The specific enthalpy change of water vapor from one state to another depends on the initial and final conditions. However, in this case, the initial condition is given as water vapor at 80 bar with a quality of 0, which implies it's in a saturated liquid state. The final condition is stated as a saturated vapor at 100 bar.

Typically, in a thermodynamic process, you would not expand a substance to a higher pressure (from 80 bar to 100 bar in this case) without external work or heat transfer. Also, the transition from a saturated liquid state to a saturated vapor state usually involves heat addition (boiling process).

If you have specific enthalpy values for the initial and final states from a steam table, you can calculate the change in specific enthalpy (∆h) using the formula:

∆h = h_final - h_initial

However, with the given information, it's not possible to provide a numerical answer. Please check the problem statement or provide additional information.
