Question

In which phase transition do molecules directly move from state to state involving a vibration of particles in a fixed position to a state involving random movement of high speed particles 
Evaporation 
Sublimation 
Freezing
Depostion

Fixed state means solid

Random movement means gas

The phase change from solid to gas without first becoming a liquid I believe is sublimation.

Think about frozen CO2 (dry ice)
