The rate of evaporation increases with

Correct option is D

Correct Answer:D. All of the above

• The rate of evaporation depends on several key factors. Each of the options contributes positively to increasing evaporation:

  • Increase in surface area:
    More molecules are exposed to air, allowing more to escape as vapor.

  • Increase in temperature:
    Molecules gain more kinetic energy, making it easier to overcome intermolecular forces and evaporate.

  • Decrease in humidity:
    Drier air allows more water vapor to diffuse into the atmosphere. If humidity is high, the air is already saturated, slowing evaporation.

• Wind speed also increases the rate of evaporation by removing the humid air near the surface.

• Examples in daily life:

  • Wet clothes dry faster on a sunny, windy day.

  • Water coolers use evaporation to lower room temperature.

• Evaporation causes cooling, which is why sweating helps regulate body temperature.
