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

I believe the correct answer from the choices listed above is the second option It is during sublimation that 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. It  is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.
