Do different liquids evaporate at the same rate

Purpose The purpose of this project was to determine if different liquids evaporate at the same rate.

Question How will liquids affect the rate of evaporation

Abstract The purpose of this project was to discover if all liquids evaporate at the same rate. The effect of evaporation on different liquids. The results collected during this investigation were That not all liquids evaporate at the same rate. To promote understanding of this topic, future research could include testing if different liquids evaporate the same in different climates.

Hypothesis If ingredients are added to water , then the rate of evaporation will slow down. This will happen because the all the other chemicals will slow them down.

Prior Research Evaporation is part of a process that could bring a liquid into a cloud until it gets filled so it can rain. Evaporation could happen any time you leave a liquid outside. If you want to try letting a liquid evaporate you want to leave it out for quit sometime (you want to do this so it has time to evaporate). Evaporation could also happen to any liquid ( but you still have to wait awhile. One question there is that’s answer couldn't be found is " In places that rain a lot, does evaporation take place in all the rains cause? " The intent of this project is to find out which liquid evaporates the fastest. The variable to be tested and changed is the liquids. Any changes will be noted by the amount of ounces the liquids have decreased, The research showed that water should evaporate the fastest.

Materials Orange juice Water Lemonade Pepsi Tea 5 measuring cups

Discussion of Results The purpose of this investigation was to determine if all liquids evaporate at the same rate. It was proposed that if more chemicals were added to water the rate of evaporation would slow down. The data showed that the chemicals slowed down the rate for some liquids, but also didn’t slow or be faster for others. The results indicated that water and tea evaporated the fastest every day. The hypothesis wasn't supported because water and tea evaporated the fastest, not just water. Prior research indicated that liquids with the faster boiling rate evaporated the fastest. The results were as expected and were determined to be reliable because we knew tea and water would be commonly used as boiling water. The experiment was a valid test of evaporation because all liquids were poured the same amount and were in the same climate.

Conclusion The effect of evaporation was investigated in this experiment by setting different liquids in the sun and seeing which one evaporated the fastest. The suggested hypothesis was that if more chemicals were added to water the rate of evaporation would slow down. The hypothesis was supported because tea evaporated faster than most liquids. Prior research indicated that liquids that boil faster will evaporate the fastest. The results are significant because tea was the thickest liquid.

Future Research The current hypothesis could be refined to reflect the observations made during the investigation to focus on changing the outdoor temperature of the liquids. This could be tested by going and experimenting in a different states. It could also be tested by freezing the liquids before testing them.
