answered 12 May 2026Differentiate between boiling and evaporation based on at least three key characteristics.
A.VERIFIED ANSWERfact-checked by tutors
1. Boiling is a bulk phenomenon, occurring throughout the liquid when it reaches its boiling point, whereas evaporation is a surface phenomenon, occurring at all temperatures.
2. Boiling involves rapid bubble formation, while evaporation is a slow and continuous process.
3. Boiling occurs at a fixed temperature (boiling point), while evaporation can occur at any temperature below the boiling point.
Explanation:
Boiling is a phase transition that requires a specific temperature and involves the entire mass of the liquid, whereas evaporation is a continuous process driven by the kinetic energy of surface particles and can occur at various temperatures.
