Question

Which of the following is/are about vapourisation?

• A. a phase transition from the liquid phase to vapor
• B. there are two types of vaporization namely evaporation and boiling
• C. evaporation is a surface phenomenon, while boiling (vaporization) is a bulk phenomenon
• D. evaporation is a bulk phenomenon, while boiling (vaporization) is a surface phenomenon

Answer 1

Answer: (A), (B), (C)

The correct options are
A a phase transition from the liquid phase to vapor
B there are two types of vaporization namely evaporation and boiling
C evaporation is a surface phenomenon, while boiling (vaporization) is a bulk phenomenon

Vapourisation of compound is a phase transition from the liquid phase to vapor. There are two types of vaporization namely evaporation and boiling. Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon. The other two options fails to explain the difference between vaporization and evaporation properly.
