Question

The rate of evaporation of water from the liquid ink decreases as _______ during the extraction of dye from blue or black ink.

• A. humidity of surrounding air increases
• B. atmospheric pressure decreases
• C. movement of air above surface of liquid increases
• D. temperature increases

Answer 1

The correct option is A humidity of surrounding air increases

The rate of evaporation of water from the liquid ink decreases as the humidity of surrounding air increases during the extraction of dye from blue or black ink. Because, as the humidity of the atmosphere increases the atmospheric pressure increases. So that the rate of evaporation decreases.

Hence, the correct option is $A$
