This question is based on the concept of material science

ii) iii) For the construction of phase diagrams, instantaneous quench to a fixed temperature is assumed. The presence of vacancies in a crystal increases the entropy of the crystal. For the movement of dislocations, the combination of the slip plane and the slip direction is called a slip system. The preferred slip systems are the ones where the atomic distortion that accompanies the motion of dislocation is minimum.
