Evaporation is a surface process, boiling is a bulk process. Deposition is the direct transition from gas to solid. Phase changes depend on both temperature and pressure.
Which of the following is correct? 1. Evaporation is a surface phenomenon, which means particles from the surface change into the vapour state. 2. Boiling is a bulk (whole) of the liquid change into vapour state. 3. Deposition is the change of gaseous state directly to solid without converting into the liquid state. 4. The state of matter can be changed by changing its temperature only.
