Phase changes (solid, liquid, gas) are influenced by both temperature and pressure. Evaporation is a surface phenomenon, while boiling is a bulk phenomenon. Deposition is the phase transition from gas to solid.
Consider the following statements: 1. Evaporation is a surface phenomenon, meaning particles from the surface change into vapour state. 2. Boiling is a bulk phenomenon, meaning particles from the bulk of the liquid change into vapour state. 3. Deposition is the change of gaseous state directly to solid state without changing into liquid state. 4. The state of matter can only be changed by changing its temperature. Which of the following is correct?
