When temperature increases, would the density of water go up or down? now, I know ice is less dense than water, but doesn't the density of water also go down once heated? If that's the case, when does it increase? That's mostly just a side question, lol, the main question is would it definitely go up or down when heated.
Above this point heated water will expand and get LESS dense.
Below 0 deg C, water normally freezes (becomes solid);
however under special circumstances, as water is cooled to below that temperature the density of water will decrease.
