Question

Rate of evaporation of water increases as ________ during the extraction of colored substance from the liquid ink.

• A. exposed surface area of liquid decreases
• B. movement of air above surface of liquid decreases
• C. exposed surface area of liquid increases
• D. atmospheric pressure increases

Answer 1

The correct option is C exposed surface area of liquid increases

Rate of evaporation of water increases as exposed surface area of liquid increases during the extraction of colored substance from the liquid ink, because the evaporation is the surface phenomenon. So the rate of evaporation is directly proportional to surface area of the liquid.
