Introduction
Welcome to the world of Science and Evaporation.
My experiment is about household liquids. It is to check which household liquid evaporates the fastest and why?
I am doing this experiment because I have always been puzzled by disappearing liquids when the bottle was left open.
I conducted this experiment on a Sunny Day………………. And got the following results.

Aim
The aim of this experiment is to find out which household liquid will evaporate the fastest and why?
Apparatus

· Labels.
· Bowls.
· Paper.
· Pen.
· Stop watch.
· Household liquids:-
o Nail Polish Remover.
o Whisky.
o Vinegar.
o Listerine.
o Coke.
o Red Wine.
o Lime Juice.
o Water.
o Milk.
o Oil.
· Labels.

· Household liquids:-
o Nail Polish Remover.
o Whisky.
o Vinegar.
o Listerine.
o Coke.
o Red Wine.
o Lime Juice.
o Water.
o Milk.
o Oil.
Variables
· Amount of liquid left (ml) after fixed time intervals (2 hours).
· To be kept constant – Temperature (Air and liquid).
· To be kept constant – Initial Quantity of liquids (20 ml).
· To be kept constant – Humidity.
· To be kept constant – Size of the bowls in which the liquids are left to evaporate.
Method:
1. Measure 20 ml of each of the ten liquids being tested and pour into separate labelled bowls.
2. The bowls are left exposed to the air in the backyard on a wooden deck.
3. Every 2 hours each liquid that remained in the bowls is carefully measured with a measuring cup and the quantity left was noted in the results table.
4. Repeat step 3 at 2 hours, 4 hours, 6 hours, 8 hours, 10 hours and 12 hours and the results are recorded.

Conclusion
My hypothesis was proved correct, as the nail polish remover evaporated the fastest because it was a thin liquid while the other liquids were thicker. Oil and milk did not evaporate as much as the others did; Coke and whisky also did well. The whisky was evaporating very fast at first but gradually it grew slower because the alcohol in it had evaporated first and the water takes a long time to evaporate. That is why the whisky evaporated slower at the end. The nail polish remover is all alcohol based so it evaporated quickly but after the alcohol had gone at 4 hrs and 27 mins, there was some thicker fluids left that took 5 hrs and 33mins to evaporate off completely.
Application
The Most Commonly known and experienced phenomena of the process of evaporation is the water cycle. Water from land evaporates and finally results in rainfall. Another application is that salt is produced by evaporating sea water. My experiment shows us that you should take care to shut all bottles of household liquids tight, or you just might find you lost your whisky or nail polish remover all gone!!!!!
Discussion
My graphs show a relationship which is that as the time increases the volume of the liquids decreases.
Possible Errors:
Ø Measuring of the liquids.
Ø Due to surface tension some liquids like oil and milk tend to stick to the container they are stored in.

Thank You for looking at my Science Fair it was highly appreciated I hope you learned something about science and evaporation
