Homework Help: chem

Posted by david on Thursday, March 29, 2007 at 9:01pm.

confused about this one.

2 samples of water of equal volume are put into dishes and kept at room temp for several days. the water in the first dish is completely vaporized after 2.8 days while the water in the second dish takes 8.3 days to completely evaporate. What can you conclude about the two dishes?

This one is confusing me because both are water in the same enviornment but different evap. times?? So the water shouldn't be water?

Help me out!

thanks

Wouldn't surface area matter? One could be in a long neck tube vase, the other in an evaporating dish.

Jeez, I didn't think about that...
