Explanation:
answer 1. Sample B the evaporation of water will be faster because the rate of evaporation will be faster in sample B , where the dish is kept under the fan. This is because when the wind is blowing, it makes the rate of evaporation faster.
answer 2.If the same experiment is carried out on a rainy day, the water will not evaporate too much. This is because -During the rainy season, humidity content in the air is high. So if the air is already laden with moisture, there is not much chance of the water evaporating into the atmosphere .During rainy days, the temperature is low, so the rate of evaporation will be slower. The rate of evaporation depends upon the amount of sunlight received. More is the sunlight, faster is the rate of evaporation. During rainy days, sunlight is not much. And if winds blow faster, rate of evaporation will also be faster.
answer 3.Evaporation is a surface phenomenon. If the surface area is increased, the rate of evaporation increases. While putting clothes for drying up, we spread them out, because, more area is exposed to sun and wind which speeds up the rate of evaporation.
