We know that ordinarily, pressure, volume, and temperature cannot change individually without one affecting the other. Yet when a liquid evaporates, its volume changes, even though its pressure and temperature are constante. Is this inconsistent?
(From University Physics with Modern Physics 13th Edition)
I think it is inconsistent because when, for example, water evaporates two things occur:
- The temperature remains constant. In phase transition, the water temperature remains unchanged.
- The pressure CHANGES because there is less volume.
I am not very confident with the second part (2).
What do you think?
