Question 2
Kinetic Theory and States of MatterChanges in the physical states of a chemical substance T are shown in the scheme below.
The letters X, Y and Z respectively represent
- A.sublimation, condensation and freezing
- B.sublimation, vapourization and solidification
- C.freezing, condensation and sublimation
- D.evaporation, liquefaction and solidification
Show the answer and explanation
