    Density of water

    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.

    You know that d=\frac{m}{v}, so... what do you think will happen when the water is heated?

    From 0 to 4 deg C, when heated, water was get MORE dense. Water is most dense at about 4 deg C.

    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.
