Guest Posted April 6, 2010 Report Share Posted April 6, 2010 There are two absolutely identical bottles placed in outer space, one containing a liquid and the other empty. You cannot see the inside, and are not allowed to move either of them. How do you determine which contains the liquid? Quote Link to comment Share on other sites More sharing options...

0 Guest Posted April 6, 2010 Report Share Posted April 6, 2010 What do you mean "cannot see the inside"? Are the materials opaque to all forms of electromagnetic radiation? If not then...X-ray diffraction. Magnetic resonance imaging. Quote Link to comment Share on other sites More sharing options...

You cannot see the inside, and are not allowed to move either of them. How do you determine which contains the liquid? a liquid at room temp on earth, or a liquid in outerspace? differnt things have different properities in different places!

0 Guest Posted April 8, 2010 Report Share Posted April 8, 2010 Could it be that the bottle containing liquid will be floating slower than the empty bottle??? Quote Link to comment Share on other sites More sharing options...
0 Guest Posted April 9, 2010 Report Share Posted April 9, 2010 Unless the "empty" bottle was a vacuum, both bottles would contain solids, not liquids. With an average temperature in space of 3 degrees kelvin (3 degrees above absolute zero) even air would freeze and become solid substance.

0 Guest Posted April 10, 2010 Report Share Posted April 10, 2010 The bottles have different mass. Just as on earth, if you shake the bottles side to side, you can feel the difference in weight (mass). Quote Link to comment Share on other sites More sharing options...

This was discussed among my friends and the guy who put it forward said this answer by palascosas is the right answer. However we weren't exactly in agreement so that's why I posted it here to get a better feedback. I see that there is not a definitive answer here actually.
