Title
Evaporation of different liquids

Broad Question
how does heat affect the evaporation rate of different liquids?

Hypothesis
It is hypothesized that water will evaporate the fastest.

General Plan
I am going to run my experiment between the dates of march 4th to march 21st. My independent variable will be my types of liquids and the three different types of liquids will be water, tea, and orange juice. My experiment will be held in my closet upstairs and the temp will be room temp, I will set up three heat lamps and three tables with the heat lamps pointed directly at the liquids and I will mark where the liquid is in every cup every single day until the experiment is over and each cup will be plastic and have 200ML of the liquids. While I mark the liquids everyday I will observe which liquid will evaporate the most. after conducting my first trial I will see if there are any flaws and if there is I intend to fix them and conduct my experiment a 2nd time.

Potential Problems And Solutions

Background Research
This is in part related to the concentration points above. If fresh air is moving over the substance all the time, then the concentration of the substance in the air is less likely to go up with time, thus encouraging faster evaporation. This is the result of the [|boundary layer]  at the evaporation surface decreasing with flow velocity, decreasing the diffusion distance in the stagnant layer. [|Pressure] Evaporation happens faster if there is less exertion on the surface keeping the molecules from launching themselves. [|__Surface area__] A substance that has a larger surface area will evaporate faster, as there are more surface molecules that are able to escape.

Others do likewise around the world. The US data is collected and compiled into an annual evaporation map. <span style="background-color: transparent; color: #0645ad; font-family: Arial; font-size: 13px; text-decoration: none; vertical-align: baseline;">[|[2]] <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 13px; text-decoration: none; vertical-align: baseline;">The measurements range from under 30 to over 120 inches (3,000 mm) per year.
