jdurg Posted January 16, 2005 Share Posted January 16, 2005 Yeah, it will happen with any substance whose solid form is less dense than its liquid form. Link to comment Share on other sites More sharing options...
budullewraagh Posted January 16, 2005 Share Posted January 16, 2005 well yes, but the only things that have this property i listed above Link to comment Share on other sites More sharing options...
JLB Posted January 17, 2005 Share Posted January 17, 2005 Thank you. Question resolved. I understand that it's highest density is at +4C. That ~ meant ? Link to comment Share on other sites More sharing options...
budullewraagh Posted January 17, 2005 Share Posted January 17, 2005 actually it's 3.98 celsius according to lange's interestingly enough you can calculate water's max density at a given pressure (var "p" in atmospheres) by the equation: tm=3.98-0.0225(p-1) but yeah, at higher temps collision rates increase, thus making it less dense. you would think that the greatest density would be the positive limit as the temperature approaches 0 (yeah calculus) but instead, since water doesn't all melt just above 0 celsius, 3.98 celsius is the temp at which the maximum density is achieved Link to comment Share on other sites More sharing options...
