Evaporation is a _ process.
Correct answer: B. Spontaneous
- A. Exothermic
- B. Spontaneous
- C. Non-Spontaneous
- D. None of these options are correct
Explanation
A process that can take place by itself under the given set of conditions once it has been initiated, if necessary, is said to be a spontaneous process.It can be slow or instantaneous.If water is kept in sunlight, we cannot predict or see when the water molecules evaporate hence, it is a spontaneous reaction.

About Evaporation, Boiling Point and Vapour Pressure
Evaporation is the escape of higher-energy molecules from a liquid surface, while vapour pressure is the pressure exerted by vapour in equilibrium with that liquid. The topic distinguishes evaporation from boiling and relates both to temperature, intermolecular forces, surface area, atmospheric pressure and the boiling point.
