Because the total enthalpy you end with is not dependent on the process you took to get to that point (like if I boil a pot of water and tell you it initially was 80 degrees and now its 150 degrees.

Because the more energy provided the more the substance starts to become the next phase, but this energy must go to maintaining that phase so increasing heat won't increase temperature until the substance has completely achieved the next phase

Because delta H = enthalpy of final(or product) - enthalpy of initial(or reactant).
