Do all liquids evaporate at the same rate?

Materials:

Water Orange juice Alcohol Nail polish remover Four beakers with measures Pen and paper for notes

Procedure

1.Firstly,pour the same amount of liquid into each beaker. Note the amounts. 2. Then you set the beakers in a dry location at room temperature. 3. Monitor the levels of the liquids for 1 week and note any differences.

How does liquid become a gas?

Hypothesis

According to me, 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 .But they will not evaporate at the same rate because water will evaporate faster than the other liquids since that all the chemicals in the other liquids will slow them down.

My Result

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 .

Conclusion

I realized that 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.
