Question

In which phase transition do molecules directly move from a state involving vibration of particles in a fixed position to a state involving random movement of high-speed particles?
a. evaporation
b.sublimation
c.freezing
d. deposition

aaronq · Answer

fixed position  = solid

random movement of high-speed particles = gas


solid -> gas  transition = sublimation
