- X represents the transition from Solid T to Gaseous T. This process is called sublimation.
- Y represents the transition from Gaseous T to Liquid T. This process is called condensation.
- Z represents the transition from Liquid T to Solid T. This process is called freezing or solidification.
Therefore, X, Y, and Z respectively represent sublimation, condensation, and freezing.
Comparing this with the given options:
A. sublimation, condensation and freezing
B. sublimation, vaporization and solidification
C. freezing, condensation and sublimation
D. evaporation, liquefaction and solidification
The correct option is A.
The final answer is A
