Question

Statement I: On increasing the surface area of any liquid at constant temperature, the rate of evaporation increases. Statement II: Increase in surface area at constant temperature increases the escaping tendency of molecule of liquid at surface.

Prashant Kotian · Accepted Answer

Correct answer: C. Evaporation is a surface phenomenon. Increasing the surface area increases the rate of evaporation because more molecules are exposed at the surface to escape. However, the intrinsic "escaping tendency" (vapor pressure) depends only on temperature and is independent of surface area. Thus, Statement II is incorrect.
