Homework Help: SCIENCE AGAIN

Posted by Pat on Friday, December 8, 2006 at 12:16pm.

Thanks so much for all your help. These multiple choice questions always have me confused. Here goes: The density of fresh water either a.)reaches a maximum at 4 degrees C, b.)decreases with decreasing temperature below 4 degrees C, c.)increases with decreasing temperature down to 4 degrees C, d.)all of the above,or e.)none of the above. I know that the density of fresh water reaches a maximum at 4 degrees C and it cannot be none of the above, but what about all of the above. Please help again. Thanks

Here is your answer. The easy answer to your question is to look at a table
of density of water at various temperatures. This site doesn't give a table but it provide exact asnwers to each of the above.
