On a p-v diagram, there are constant temperature lines. If the process line is parallel to that of specific volume(that is, constant pressure inside the saturation dome), is there any change in internal energy?

    So that means there should be no change in internal energy for process 1 to 2, correct? Anyone??

    although in the saturation dome the temperature remains constant and internal energy must remain same..but it is not true..internal energy not only depends on the temperature of a substance but also at its state(vapor or liquid)..at points 1 & 2 although temperature is the same but there is a difference in the dryness fraction(mass of vapor present/total mass) ie. amount of the vapor hence the internal energy will not be the same..:)
