Question

Which of the following are differences between evaporation and vaporisation?

• A. Evaporation occurs at all temperatures but vaporisation occurs at fixed temperature only
• B. Evaporation is a slow and gradual process whereas vaporisation is a rapid and violent process
• C. Evaporation takes place only at the surface of the liquid whereas vaporization takes place over the entire liquid
• D. Evaporation happens all the time in a day whereas vaporization happens only once a day

Answer 1

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

The correct options are
A Evaporation occurs at all temperatures but vaporisation occurs at fixed temperature only
B Evaporation is a slow and gradual process whereas vaporisation is a rapid and violent process
C Evaporation takes place only at the surface of the liquid whereas vaporization takes place over the entire liquid

The differences between evaporation and vaporization are:

1. Evaporation occurs at all temperatures but vaporisation occurs at a fixed temperature only that is the boiling point.

2. Evaporation is a slow and gradual process whereas vaporisation is a rapid and violent process.

3. Evaporation takes place only at the surface of the liquid whereas vaporization takes place over the entire liquid.

4. Evaporation causes cooling but vaporization does not produce cooling.
