Question

what do you infer about the effect of temperature, surface area and wind velocity (speed)on evaporation

Answer 1

Temperature - more is the temperature more will be the rate of evaporation. In other words, temperature is directly proportional to evaporation.
Surface area- more is the surface area, more will be the rate of evaporation. In other words, it is directly proportional to evaporation.
Wind- more is the speed of wind, more will be the rate of evaporation. In other words, speed of wind is also directly proportional to evaporation.
