... will evaporate faster the hotter the water is underneath it. Method: See Plan. Diagram: Results: Test 1 Test 2 Temperature Of Water ( C) Volume Of Alcohol Left (Ml) Volume Of Alcohol Left (Ml) 70 9 9 60 9.3 9.2 50 9.4 9.3 40 9.5 9.4 30 9.7 9.7 Conclusion: I found out that the hotter the water underneath the alcohol, the quicker it evaporates.
