bnrmom Posted November 16, 2011 Share Posted November 16, 2011 The question is: Suppose that you have one teaspoon of sugar and one tiny grain of sugar. Compare their properties. I really have no idea what they are looking for - ds's answer was that the teaspoon has more sugar molecules. :tongue_smilie: It's in a chapter on movement of molecules, so I'm thinking it has something to do with that? (This is the problem with using a textbook with no answer key. :glare:) Quote Link to comment Share on other sites More sharing options...
Chris in VA Posted November 16, 2011 Share Posted November 16, 2011 Well, that's an odd question. The quantity of a substance doesn't change the properties of it! Quote Link to comment Share on other sites More sharing options...
bnrmom Posted November 16, 2011 Author Share Posted November 16, 2011 Well, that's an odd question. The quantity of a substance doesn't change the properties of it! That's what we thought! Could it be something about a group of solid molecules moving in a certain way? Quote Link to comment Share on other sites More sharing options...
WVNA Posted November 16, 2011 Share Posted November 16, 2011 Are they the same form of sugar? For example, are you comparing powdered sugar in the teaspoon with a grain of sugar? I haven't done the experiment, but I would guess there would be effects related to dissolving the sugar in water as well since there is more surface area exposed in powdered sugar to interact with moving water molecules. You are right though, a sugar molecule should be the same in both cases so the chemical properties shouldn't change. Quote Link to comment Share on other sites More sharing options...
