Which of the following does not increase the rate of evaporation ?
Decrease in temperature
The correct answer is option 4 I.e. Decrease in temperature.
'Decrease in temperature' does not increase the rate of evaporation — in fact, it decreases it.
Evaporation is faster when:
-
Temperature increases (more energy for molecules to escape)
-
Surface area increases
-
Air flow (wind) increases
-
Humidity decreases
So, a decrease in temperature slows down the movement of particles, thus reducing the rate of evaporation.
