What Affects the Rate of Evaporation in Different Liquids

What Affects the Rate of Evaporation?
Aim
* To find out if changes in temperature, draught and surface area of water open to air affects the rate of evaporation through the water. * To safely check if these variables change the rate of evaporation * To complete all the experiments in the short period given
Prediction
* I believe that a raise in temperature will speed up the rate of evaporation in the water * I believe that a larger surface area will speed up the rate of evaporation in the water * I believe that draught will not affect the rate of evaporation, or at least the rate at which it does affect evaporation will not be able to be measured in the short time available for each experiment
Temperature
* Bunsen Burner * Tripod * Heat Mat * Gauze * Beaker * Measuring Cylinder * Water * Thermometer * Safety Goggles * Gloves * Tongs * Scales

Control Variables * In this experiment the control variables are the volume of water we use for each beaker. If we change the volume of water for each beaker, the results we get will not be relevant, since we are seeing what affects the rate of evaporation, and the more the volume of water, the slower the rate of evaporation. Therefore in this experiment, we are keeping the volume of water at 100ml. To do this well, we will use measuring cylinders to measure 100ml, then use the scales to make sure the same mass of water is used in each experiment. * Secondly, in this experiment, the size of the beaker must be kept the same because a bigger beaker can mean a larger surface area open to the air, and surface area could affect the rate of evaporation, meaning our results will be inaccurate. Therefore, for each test we checked that the beakers were all the same size using rulers. * Thirdly time must be controlled in this experiment. If we change the amount of time heat is applied to the water, our results will not be relevant. The longer the heat
