Why boiling is called bulk phenomenon?
Understand the Problem
The question is asking for an explanation of why boiling is referred to as a bulk phenomenon, which typically involves discussing the nature of boiling as a process that occurs throughout the volume of a liquid rather than at just the surface.
Answer
In boiling, the entire liquid mass gains energy to become vapor, making it a bulk phenomenon.
Boiling is called a bulk phenomenon because it involves the entire mass of the liquid. During boiling, particles throughout the liquid gain enough energy to turn into vapor, not just those at the surface.
Answer for screen readers
Boiling is called a bulk phenomenon because it involves the entire mass of the liquid. During boiling, particles throughout the liquid gain enough energy to turn into vapor, not just those at the surface.
More Information
Unlike evaporation, which only affects surface molecules, boiling affects the whole liquid, occurring uniformly throughout at the boiling point.
Tips
Mistaking boiling for evaporation; remember that evaporation is a surface phenomenon while boiling involves the entire liquid.
