Transcript of Do All Liquids Evaporate At The Same Rate?

Procedure
step 1 - pour the same amount of liquid into each cup ,and note the amounts
step 2-set the cups in a dry location at room tempature
step 3-monitor the levels of the of the liquids for 5 days and note any differences
Hypothesis
I think that if i pour equal amounts of orange juice , water ,alcohol,and nail polish in cups and observe them to see if they evaporate at the same rate .Then I think that they will not evaporate at the same rate because i think that water will evaporate faster than the other liquids ,because I think that all the chemicals in the other liquids will slow them down.
Materials
Water
orange juice
Alcohol
Nail polish remover
Four cups
Pen and paper
Results
In results not all the liquids evaporate at the same rate .The alcohol was the fastest to evaporate and the nail polish was the second and the water and orange juice were evaporating at a slow rate .
variables
independent variable:room tempature
dependent variable:The days observing the rate the liquids evaporate
constant variable:the cups
Conclusion

iiiiiooo
In conclusion my hypothesis was wrong because all the other liquids evaporated faster than the water.Alcohol was the first liquid that evaporated faster than the others because it has a low boiling point and the nail polish remover was the second liquid to evaporate because it contains acetone which has intermolecular forces than water which causes evaporation at a faster rate .And the orange juice was evaporating at the same rate as the water.
Data
Day 1 :Alcohol has gone down a
2
inches ,nail polish remover has gone down a inch ,orange juice and water stayed the same
Day 2 :Alcohol has gone down a inch again ,nail polish remover has also gone down a inch ,orange juice and water have gone down a
1
inch
Day 3:Alcohol has gone down
2
inches ,nail polish remover has gone down
1
inch , water and orange stayed the same
Day 4:Alcohol has gone down
2
inches again ,nail polish remover went down
2
inches ,water and orange juice went down
1
inch
Day 5 : Alcohol has gone 1 inch ,nail polish remover has gone down 2 inches ,water and orange juice went down 1 inch
