Well, since there's nothing forcing the ice down into the water, the volume of water displaced by the ice has a mass equal to the mass of the entire icecube. So B would be the "right" answer. On 9/29/05, Henry Baker <hbaker1@pipeline.com> wrote:
Good point! Based on what we've been hearing about some of these standardized tests, it may not be clear what the "right" answer is.
As I recall, the question goes something like this:
A cube of ice is floating in a glass of water that is filled to the top. (No discussion of meniscus.)
When the ice melts, the water in the glass:
A. overflows B. stays at the same level C. goes down D. none of the above
I'm sure that I said "B", but then again I didn't get a perfect score on the math SAT. Perhaps this is one question that I blew.
It is possible that slight differences in the % of deuterium between the ice & the water could change this answer (a al TK). :-) :-)

Let me see -- melting floating ice makes the water level rise? Isn't this a standard SAT question? I guess Mr Revkin's verbal SAT scores exceed his math SAT scores. ------------------
But what is the official SAT answer to this question?
