water moves less because it is lacking kinetic energy. Water forms more hydrogen bonds and they are not so easy to break. The water becomes solid and the hydrogen bonds hold the structure in a semi-crystalline form known as ice. Properties and importance of Water Solvent: The solvent properties of water make it

Chapter 5: Water and Seawater • Water has many unique properties, both chemical and physical. • Salts and other dissolved compounds in seawater. • Ocean water salinity, temperature, and density vary with depth. Water's structure defines its many properties • Atoms – building blocks of all matter • Subatomic particles – Protons – Neutrons – Electrons • Number of protons distinguishes chemical elements Water is a molecule • Strong covalent bonds between one hydrogen (H) and

bonds with each other. This are continuing breaking and reforming, so the molecules can move around. Property of water Solvent Importance Metabolic processes in all organisms rely on chemicals being able to react together in solution Examples 70-95% of cytoplasm is water. Dissolved chemicals take part in processes such as respiration and photosynthesis in living organisms Liquid The movement of materials around organisms, both in cells and on a large scale in multicellular

water is less dense in the form of ice, this property is crucial to the survival of aquatic habitants, this means lakes and ponds freeze from top to bottom rather than vice versa. Ice is an insulator and delays freezing of the water beneath it. Importance of water to living organisms Water is the main constituent of all organism, up to 98% of a jellyfish is water and mammals are typically 65%
