WebJun 23, 2024 · Updated on June 23, 2024. Water is unusual in that its maximum density occurs as a liquid, rather than as a solid. This means ice floats on water. Density is the mass per unit volume of a material. For all … WebHowever, when salt is added to the cold water, it increases its density and makes it denser than the warm water, meaning that it can remain as a stable layer over the warm water below. The salt ions take up more space than the same weight of freshwater molecules, and the resulting solution is denser. This is why the cold water can remain stable ...
WebMar 6, 2011 · Answer. Chris - Hot water is actually a little bit heavier than cold water because, as Einstein told us, E=mc2. So if E, the energy in the water, goes up because it's hotter, then mass, m, must also go up to keep the equation balanced [c, the speed of light in a vaccuum, doesn't change]. So there will be a very subtle and very tiny increase in ...
