  • Seawater - Wikipedia
    The average density at the surface is 1 025 kg L Seawater is denser than both fresh water and pure water (density 1 0 kg L at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume The freezing point of seawater decreases as salt concentration increases
