Factors Influencing Evaporation Rate

Steps:

• Identify key factors: temperature increases kinetic energy for faster evaporation; draught (wind) removes saturated air to enhance rate; larger surface area exposes more liquid molecules to air.
• Evaluate option A: high temperature boosts energy, large surface area maximizes exposure, but no draught slightly reduces rate—still overall highest.
• Compare to others: low temperature in B, C, D slows molecular escape; small surface in B, C, D limits exposure; draught helps B and D but not enough to compensate.
• Conclude A maximizes rate despite missing draught, as temperature and area dominate.

Why A is correct:

• Evaporation rate follows the formula involving temperature (higher T increases vapor pressure per Clausius-Clapeyron equation) and surface area (proportional to exposed area for molecular escape).

Why the others are wrong:

• B: Low temperature hinders despite draught and small area limits exposure.
• C: Low temperature and no draught with small area minimize all factors.
• D: Low temperature slows process even with draught and small area.

Final answer: A
