1273 - What are the different components and properties of seawater.

Seawater is made up of lots of different things. Here's a breakdown:

Components:

  1. Water (96.5%): This is the main part of seawater.
  2. Salts (3.5%): Seawater contains different types of salts, like:
    • Sodium chloride (table salt)
    • Magnesium chloride
    • Calcium carbonate
  3. Gases ( tiny amounts): Like oxygen, nitrogen, and carbon dioxide
  4. Other tiny things: Like tiny plants (phytoplankton), tiny animals (zooplankton), and dead stuff from plants and animals.

Properties:

  1. Temperature: Seawater temperature can vary depending on where it is and how deep it is.
  2. pH: Seawater is slightly alkaline (not too acidic or too basic).
  3. Density: Seawater is denser than fresh water because of the salts in it.
  4. Color: Seawater can appear blue, green, or murky, depending on the amount of tiny plants and animals in it.
  5. Conductivity: Seawater conducts electricity because of the salts in it.

Remember, seawater is a complex mixture of lots of different things, and its properties can vary depending on where you are and how deep you are in the ocean!
