Question : Which of the following factors increases the rate of evaporation?
I. An increase in surface area
II. A decrease in humidity
Option 1: Both I and II
Option 2: Only II
Option 3: Neither I nor II
Option 4: Only I
Correct Answer: Both I and II
Solution : The correct answer is Both I and II.
I. An increase in surface area: The larger the surface area, the more molecules can escape into the air, leading to an increased rate of evaporation.
II. A decrease in humidity: Humidity refers to the amount of moisture in the air. When humidity is lower, the air can hold more water vapour, creating a concentration gradient that promotes faster evaporation.
Therefore, both an increase in surface area and a decrease in humidity contribute to an increased rate of evaporation.
