Question

Observe the following diagrams for the standard molar change of a pure compound. determine Which diagrams shows a phase transition with a well-defined boundary between the Two phases. Justify your answer. (b) The liquid/vapor phase transition is a second type of transition that occur at the critical point (According to the criterion of Ehrenfest). Give two other examples of Transitions of second types, and briefly explain the nature of the two relevant Phenomena|.

Answer 1

Answer:

a) The First Graph explaines well a bout the Phase Transition. According to the Phase diagram at one of the point one phase converts in to other phase.

In the second graph phase convertion point is not there and it does not seem the single compound Graph.

b) Second type of Transitions:

Example: Ferromagnetic - Diamagnetic transitions.

In the second type of transitions the first derivatives of thermodyamic potential by temperature are 0 and the second derivatives are not 0.
