Rates of Evaporation
Landen Boysen ScifairProj
The density of water is 1.0 and the boiling point is 100ºC. The density of motor oil is 0.9 and the boiling point is 572ºF. The density of gasoline is 3.03. Motor oil boils at a higher rate than water and gas.
Acetone has a evaporation rate of 0.0133 ml/s. Also, the rate of evaporation of Benzene is 0.0166 ml/s. Chloroform has a evaportation rate of 0.010 ml/s. This information will help me form my hypothesis if I consider the density of the liquids.
My hypothesis is motor oil will evaportate faster. I base my hypothesis on the information that motor oil is less dense allowing the energy from the sun to move faster though it.
Motor oil, Water, and gasoline
3 open containers
1. Get 3 containers and put one liquid in each containaner
2. Put the liquid in the sun for 4 hours and record the starting amount of liquid
3. Record the amount of liquid in the containers at the middle and end time.
My hypothesis was Motor oil will evaportate faster. The results indicate that this hypothesis should be considered wrong. Based on the results of this experiment gasoline evaporated the fastest. If I were to conduct this science fair project again I would give it more time to evaporate.
