Question

Surface tension explains which of the following

phenomena?
I) A bowling ball sinking more slowly
through molasses than through water
II) Separating ethanol from water by distillation
III) Water beading on a windshield during
the rain
1. I and III
2. I, II and III
3. III only
4. II and III
5. I only
6. II only

Answer 1

I'm pretty sure the answer is 1. I and III

Answer 2

III only. Surface tension caused liquids and in this case water, to bead. The first, sounds like density, and distillation doesn't have anything to do with surface tension.
