Question

A cupful of water and a cupful of gasoline are placed in a sunny window. Both cups have the same volume of liquid in them. 24 hours later you observe that both cups have less liquid in them, but there is less gasoline than water. What can you conclude from this observation?

Answer 1

gasoline evaporates faster?

Answer 2

I can conclude that the gasoline has escaped due to it's less forces of attraction between the molecules and evaporation and water has also escaped in water vapours due to evaporation but still is more than gasoline because of more force of attraction between the molecules of water (liquid).

Hope this helps :)
