Does hot water weigh more than cold water?

Except around 4 Celsius (39 Fahrenheit). Water is most dense around that temperature, which means water at freezing point (0 Celsius / 32 Fahrenheit) is lighter than water at a slightly higher temperature. Beyond 4 Celsius, the warmer the lighter. Thu May 11 08:38:20 CDT 2000 (Reposted to fix characters - McG) May 05 02, 7:21 AM

Cold water does weigh more than hot water because it is more dense at a colder temperature. The strange thing about this behavior is that once the water freezes and forms ice, the ice is less dense than the water. Ice floats because the weight of the water that the ice displaces is greater than the weight of the ice itself. This is the principle of buoyancy. The difference in the two weights is the buoyant force acting on the ice. The same volume of water can have two different weights, if one is liquid and the other is solid [ice] because the density [weight per unit volume] of liquid water is greater than the density of ice. Water is one of the very few materials that exhibit this behavior. http://www.madsci.org/posts/archives/oct99/938912847.Es.r.html http://www.madsci.org/posts/archives/mar98/891038833.Ch.r.html Feb 08 08, 1:33 PM

Why does hot water clean dishes better than cold water? Hot water is heavier than cold water, true or false? Is it true that when making ice cubes, hot water freezes quicker than cold? Does sparkling water weigh less than normal water, and if yes, by how much?
