Which condition out of the following will increase the evaporation of water?

The correct answer is an Increase in the temperature of water.

• Increase in the temperature of water will increase the evaporation of water.
• Evaporation is the process where a liquid is converted into its vapour and removed from the evaporating surface.
• Energy is required to change the state of the molecules of water from liquid to vapour.
• An increase in the temperature can provide this energy.
• The driving force to remove water vapour from the evaporating surface is the difference between the water vapour pressure at the evaporating surface and that of the surrounding atmosphere.
• As the surface area of the evaporating surface increases, the rate of evaporation increases.
• Humidity also affects the rate of evaporation.
• As evaporation proceeds, the surrounding air becomes gradually saturated and becomes more humid.
• The process, hence, will slow down and might stop if the wet air is not transferred to the atmosphere (decrease in the humidity of the air).
• The replacement of saturated air with drier air depends greatly on wind speed.
• Hence, surface area, temperature, humidity and wind speed are factors affecting the evaporation process.
