Variations in Temperature Properties of Pure Water Latent heat of fusion : water requires a large loss of energy to pass from liquid to solid phase Reverse is true for latent heat of vaporization Meaning: large bodies of water resist changes in temperature, life processes remain constant Physical Variables: density already mentioned as an aspect of fluids pure water is most dense at 4 o C below this it becomes less dense and freezes at 0 o C when you add impurities to water (e.g., salt), its density increases thus, seawater freezes at a lower temp (-1.4 o C) if seawater can freeze, why doesn t it accumulate at the bottom of the ocean?

true for latent heat of vaporization Meaning
less dense
as an aspect of fluids pure water is most dense at 4 o C below this it becomes less dense and freezes at 0 o C when you add impurities to water (e.g., salt), its density increases thus, seawater freezes at a lower temp (-1.4 o C T:already
