Question
Density of sea water

Answer

  • Temperature and salinity are the two properties of sea water that control the density of the sea water.
  • If temperature reduces, density of water increases.
  • Cold water is denser, and so is saline water.
  • As compared to salinity, temperature affects the density more. Hence, sometimes, more saline water has lower temperature at the surface.
  • Sea water having higher temperature and low salinity, can have lower density.
