Descripción
Evaporation is the process of water transferring from a liquid to a gas and is the primary method for water to move into the atmosphere during the water cycle. Scientists believe that the earth’s oceans, seas, lakes and rivers provide 80-90% of the moisture in the atmosphere. The rest comes from plant transpiration.In this experiment, the independent variables include heat and air flow. The dependent variable is the rate of evaporation measured in time. The constants include the sponges, the plastic plates and the amount of water.What is the effectof wind and temperature on the evaporation rate of water?These two elements will be tested separately and combined to assess the overall range of effects.
